GTA3 doesnt start

[ka0tic]

Heres the story:

gta3.exe ran fine until this morning when i opened the exe file. everything started up like normal, so i went to the display setting changed it to my setting 1024x768x32 and pressed enter. all of a sudden the game closes and it says it cant support it....then a fatal exception error pops up (and yes the 1024x768x32 setting had worked perfectly b4) so i go to restart gta3.exe and it would pause for a second and then it would stop....nothing would come up it was as if i didnt even click the .exe, so i rebooted my computer retransferred all the files and it still doesnt work...any suggestions? could have anything to do with the registry? or anything? please help me
