Problem durring application startup :S

Hi, I have a smaller problem opening one of my applications, the application in concern is GTA San Andreas. When I double click the icon, it starts loading for aproximately 4-5 seconds whereafter it just stops, not even a proces is loaded. This is a later problem, since I've been able to run the program just fine for about 1-2 weeks.
When it started doing this, I found out that all I had to do was to "Run as.." and then administrator, but about 3-4 days later it started doing the same under Administrator.
I did try reinstalling it!

My suspicion is placed at the file rights system, but I have NO clue whatsoever if it's truely that?
What could be wrong?
What could I do to fix it?

Thanks

Regards, Joda

It has to be said that the error.log file has absolutely NOTHING to say about it, and the commandoprompt does the same as the double click command:
C:\Games\GTA SA\(I write>)GTA_SA.exe

[loading for about 5 sec's]

C:\Games\GTA SA\
