PC-Steam- In-Game account creation doesn't take my email address.

When I try to log in, in-game, it says my email is already in use. Tried resetting my account on the webpage, but fails it said my account doesn't exist.

I am able to sign up using the same email address via the web account creation process.

After creating account via the webpage, it will not allow me to login in-game. Checked email, and the spam folder, and no "account activation" (if there even is one) is there.

Have set my firewall to allow "crysis 2 - demo\bin32\crysis2demo.exe".

Any ideas? Want to play this!

Tried creating an account called blah_ with email blah12345666@goose.ie but it failed

Tried creating an account called blah_ but it said the username was already in use (?).

Tried creating an account called blah_3 with email blah12345666@geese.ie but it failed saying the email was already in use. geese.ie doesn't exist, and both emails were just made up.

Seems as if the demo doesn't take the email no matter what, which I find odd.

/edit2
It seems by using a non-existant email address with a name that doesn't include an underscore is the only way to get an account ingame ^.^
