I've created this username "RoTh_W3ll3s" a while ago. It was associated with an email address, name it "A". With a password, name it "a".
I was able to connect to gamesas, using "RoTh_W3ll3s"+"a" or "A" +"a". So "RoTh_W3ll3s" and "A" were linked.

For the demo i used to connect and play with this username, but using a password "b". Without creating any new account ingame nor at gamesas. How was it possible to use this kind of fake credentials ?

My today issue:
i've connected yesterday to this gamesas account. I don't remember if i've connected using " RoTh_W3ll3s"+"a" or "A" +"a", but i was then connected to this account.
I've tried to change my gamesas password, validated, unchanged, back to "a"
Later i've made changes i don't remember, but something is now broken.

Now:
i can connect at gamesas with:
"RoTh_W3ll3s" + "a" or "A" + "b".
But nor with "RoTh_W3ll3s" + "b", nor with "A" + "a"

I cant' get "a" changed: i mean, even if i validate the change to "b", it still "a", because i can't connect using "b", but "a".
And i can't get "b" changed either. I can connect to the " A" profile. But only if I use the one-time login for the email "A" account. I get then the password modification page, with "Hi, A , welcome back" on the top right of the page. But even if the modification is done, i can't then click on ""A" (in "Hi, A , welcome back"), nor Edit my profile: the website considers i'm not really connected, i get "You must sign in at the top of the page in to use the forums" and i'm not logged on this page. I have to go to the homepage to be connected as "A", and then logout.

How can I restore the association "RoTh_W3ll3s"+ "A" + "a" ?
I can't delete the "A" profile, as i can't access the Edit function.
I want to keep "RoTh_W3ll3s" as my gamesas profile, associated with "A", and change finally "a" password to "b".

Another strange thing: using my Gamespy account and password ( which is "b" in fact), i've been able to connect to gamesas. In fact gamesas as created an account (as stated by the Welcome Page and the Welcome pm) ,while i was only using the "Sign In", not "Create Account"

note:
cleaning my gamesas cookies didn't change anything to the trouble, in case you may think of cookies' corruption (or bad linking) being able to be the reason of my troubles

i need an answer !

does changing the password for the gamesas account breaks the tie between the username of the account and the email originally tied to the account ?

Is the account i log when input my email as login (showing up my email on the top right of the page) is a "real" gamesas account, considering i can't edit it at all ?

How can i link again (if this tie is broken) my username and my email ?

How can i be sure that my username was in fact really associated at the beginning with the email i thought so ?
Why the f... haven't you made visible the email associated to a username, somewhere in the editing menu of an account ( even if it were not possible to change the email) ?

Can i try to use my gamesas for the multiplayer ? If it works, should I input my redeem code through my email, even if i'm not sure it's still tied to my gamesas username ?

I don't know about the final game itself.
But this whole stuff with login issues, redeeming code issues show off a totally amateur job.
Even DICE, who had made an awful job for the BFBC2 launch/ release, had done a better job than this.

edit:
to countepart multiplayer issues: from what i've seen from the beginnig of the solo, i really like the atmosphere, spending a lot of time exploring the zones.

2 new elements:

1/ After you've changed your password from A to B for your gamesas account, associated to E email
- you can connect to your gamesas account using your username and A
- you can connect to the "E email-associated" gamesas account ("Hi, E, welcome back ! ) with B

2/ When you try to connect to gamesas with an exisiting Gamespy account ( you mustn't use it ingame; i'm nearly sur i've seen this stated somewhere), it's as if you would connect with your Gamespy Unique Nickname:
proof: enter the email associated with your Gamespy account, the password for the Gamespy account.
you'll be then logged at gamesas and you'll see at the top right: "Hi, Unique Nickname, welcome back".
BTW you can't connect with a Fileplanet / Direct2drive/Gamespy account for which the Unique Nickname has not yet been set.

Has anybody been able to solve the issue of gamesas email-username link partially (see 1/ : it proves it's not totally broken) broken after changing the gamesas password?

update.

considering the point 1/ of the above post, and that i could connect /play to the demo 2 weeks ago (and even yesterday) with my gamesas username "RoTh_W3ll3s" and the password "B" (that's why i had tried to change my gamesas account's password from "A" to "B" !!), i just gave a try to this.

I've been ble to connect to the multiplayer with:
Nickname: "RoTh_W3ll3s" ( = my gamesas account's nickname)
password: "B"

Now, the issue is that i don't know if i can try to redeem my code, using my E email and B password.
It will activate the code for sure.
But my E email seems correctly tied to my Crysis 2 Nickname, but not tied to my account's Nickname of the gamesas webpage !!
What should i do ?

Another issue:
strangely i was able to level up, but i couldn't be ranked. I'm pretty sure i've nonetheless played on both "ranked" and "custom" servers.
