Hello,
When I want to change nickname, he indicates me "Invalid password given (GS)", while I enter exactly the same password I used to connect to gamesas. Having also found my first password, I tried with this one without more success.
How do I have to make?

PS: To connect to Crysis 2 multiplayer it is necessary to me to enter the 1st password. Why?

I also have these problems.
So what I have to do?
