what can I say.. loads of unfortunate things happened with Crysis 2..
If you insist on having your "desired" username (which you already have registered on one e-mail here) on your new account, you can actually change your e-mail in a non-obvious way.
You do it through the reset password option. I did it from my @hotmail.com to now my @gmail.com. BUT FIRST I created an account in-game with the @gmail.com, then the e-mail change and the two are now connected.
Seemingly there are two databases, one for the site, one for the registered in-game accounts. It's silly, but once you make it work (hopefully like I did above), there's no problem with it.
I had to register a new e-mail, because the game has evidently detected that my hotmail.com is in use in-game..
I do however find it funny with the "missing links" here on this website.
Exhibit A: The pre-order limited edition code - where do we redeem it? It wasn't until some dude wrote "you must go to http://www.gamesas.com/redeemcode" that I personally found out how to do it.
Exhibit B: Add a payment way. No obvious way either, until I saw someone saying "you must go to http://www.mycryis.com/addcard".
A few odd things, I'd say!
But it works now and I'm thrilled by Crysis 2.
Sorry for all you peeps out there who still can't enjoy the game..
Feel free to try out my solution above and msg me if there's any progress.
N.B. If you have your redeemed code on your current account (which won't let you login to crysis 2 the game), then I'm not sure how things work, if it's transferable! I changed my e-mail BEFORE I added my code, and I'm very glad I did.
There's still some screw-up around the forums.. I'm now having two usernames on the same e-mail (darthlazze & pwnchap). I for once decided that my I'd leave my preferred nickname alone (darthlazze) and just go with Pwnchap..
But that's for people like me who have multiple usernames they prefer in-game!
