Thanks for your help guys, I pressed Yes first, then tried it again and it came back.
Launched GTA SA Singleplayer which booted up normally, tried MTA but no luck.
Deleted a file in my GTA User folder didn"t fix it too.
I turned my PC off, watched some tv for a couple of hours, when I put it back on the problem was fixed.
Karma is playing with me huehuehue.
Thanks
@MegasXLR @MADKILLER! and @Cena for your help through facebook.
