Burning Crusade Login problem

[harlequine2]

Hello

I downloaded TBC client from Warmane site, i see the realmlist is already set to the warmanes one but when i try to login, after entering id and password i see message to enter some blizzard code. Anyone else had this problem and know the solution?

@EDIT: Tried to log on my 2nd account, everything works fine, except that my other account is nondonor. I see that message "Blizzard Authenticator Code - Enter the gnrated digital code" only when i try to log on my donor-status account.

@EDIT 2: I found that already, it is because of 2 step authentication system. when im tryin to log in i'm getting message on email with the code to enter. But there is another problem, after putting that code into box message while login, it says i put incorrect password. just tried to log in on wotlk realms and all works fine so for sure my id/password is correct. any ideas?
