Help needed! I can't start Sa-MP nor Single player.

[advantage17]

When I try to start SA-MP I crash, before the game starts.
When I try to run Single player, It gives me the error that GTA San Andreas doesn't work.
I have already tried re-instaling, but it didn't help.
Does anyone know what I can do about it?

You can do one of the following:
- Go to Documents -> GTA San Andreas User Files -> Delete gta_sa.set, then try running the game.
or
- Change the name of the GTA SA Folder, then re-assign SA:MP to the new directory.

Or you could try replacing your GTA3.img, maybe you installed a mod which ruined everything.
You can download GTA3.img here :

If Re-Installing the game didnt work, your computer might have created a virtualstore that you can find on Appdate-Local-VirtualStore-Program files,
Thats what appened to me in january, since i deleted that my PC never made a backup of the game anywhere, and there for its much easier to solve problems so see if that helps if nothing like that appears Pls inform me.
