Uninstall GTA SA in Control Panel/Add or Remove Programs. Then get your saved game folder in My Documents, get the saved games folder and put the folder in desktop (Keep saved game in it!). Now, go to My Computer/Local Disk/Program Files/Rockstar Games/ GTA San Andreas and delete the folder. (Delete Rockstar Games if you have only GTA SA installed, delete GTA SA folder if you have other GTA games installed) Now get rid of all trainers and stuff. Empty recycle bin. Install GTA SA, once youre done, you can put the saved games folder back into my documents and start playing if it works. (NOTE: Im not sure if this information are true, this guide was based on how GTA VC worked, I dont have GTA SA for PC so im not certasin if TA SA is the same like GTA VC)
