Need help uninstalling superman mod

[Drummaniac17]

Ok... When I installed the superman mod for San Andreas, I forgot to backup my files. So I thought if I uninstall then reinstall the game that should fix it.... but it didn't. It's as if the mod transfered itself onto my game disc! So I tried downloading the original player.img and gta3.img files off of the internet then replacing them. That didnt work either. I used imgtool to install this mod because I didn't know about SAMI then, and this mod will NOT come off of my computer. Does anyone know how to help me?
