ye thats what i mean. i put in my user name and password (checked in email and its defiantly right) press next, nothing....
gonna try putting my key in manually with some help. lol
edit:
ye that worked perfect, for anyone with the same problem who bothers to use the search,
goto https://community.multitheftauto.com/
and sign into your beta account. find your serial, under my view.
then goto your start bar and use run (or press windows key + r)
type in regedit.
find HKEY_LOCAL_MACHINE\SOFTWARE\Multi Theft Auto: San Andreas
open that and create a new string called Username.
and set the value to your mtabeta account user name.
then create one more string named Serial then inside that you type your serial
then run the game.
