First of all, try running SAMP in administrator mode. You could also try renaming your San Andreas directory. By that, I mean renaming the "GTA San Andreas" map to another name. I use GTA San Andreas 2. Now, when you do this, and open up SAMP, it will ask you to locate your SA directory. Just search for GTA San Andreas 2 or any other name you changed it to, and pick that. Your SAMP should now work fully. If you have any ENB's, or other heavy mods, try deleting these aswell. Good luck, hope I helped!
