So yeah I had the game. I played it and saved the game. I put the saves on my F: partition and after that there was a series of windows changing extravaganza on C: .
I got the game a second time, I installed it and put the saves. Whenever I load some of these saves though, the save bar fills out, the screen fades out, a second passes, and "gtasa.exe has stopped unexpectedly".
If anyone could tinker a bit the files and fix the problem, here they are: http://www.mediafire.com/?r1sm37bbdcwbn4o
