So i press on the steam login and this error code pops up where it says quote on quote- Error / Login Failed PASSWORD EXPIRED!! Your password has expired, you will need to choose a new password before logging in. Please log in the Gamersfirst website at www.gamersfirst.com to change your password. (error code 11002). And idk what i should do i tried making a ticket but it wouldnt let me submit it and i played the game years ago i just thought back at it and wanted to get back into it but i cant seem to get into my old account where i have my weapons money cars cosmetics and what not.. So i hope one of you can help me figure out getting my old account back..
