Hey everyone, I've found that by creating a nickname WITHOUT any special characters, I can login to the Crysis 2 multiplayer suite perfectly.
However, this does not alter the fact that I've already redeemed my codes on a nickname that contains an underscore (I didn't know about the special characters problem at the time), and as such WON'T let me login to access my limited edition goodies.
Is there ANY way to change the nickname? Because I can't find it here.

HELP PLEASE!!
