When I try to login to Crysis Wars with latest patch I get Invalid username or password but the info I write in is correct, what can I do to fix this?

test to create a new account

my registration code has been us 2 time what do i do?

Are you sure you are writing in the right "username"?
A friend of mine had the same problems with this too. If i remember right he used the email instead as username or something, atleast it's worth a try.
