Sudden Attack login problem

Hi, I downloaded SA minutes ago. Created acc and that stuff.
When I try to login I get error -64(-4). Wdf does that mean?

You must be saying Error code 61(4) cause no such error as Error code 64(4). It meant that your account is inactive- Which is you did not login your account for too long. Create another new account.

U not confirmed ur Acc! go in Sudden Attack Webpage and make login, after modify urs informations
