Account activation error

I am trying to log in to my account it shows your user name or password is incorrect or your account is not activated but I activated my account so kindly help I am new to this game

Try logging into the store and if that doesn’t work request your password from there: Gaijin.Net Store

Is there a chance your caps-lock key might be turned on? The game distinguishes between lowercase and uppercase in the password field (but not the id/name field).
