GTA Vice City nocd problem!

[Refused]

Hi, I am currently using the no cd crack and when I replace my gta-vc.exe with the cracked one, all that happens is my cursor turns to a timeglass for a second , and no application opens, when I check my processes, it shows the .exe being executed, but after that second after I 2x click the icon, it dissapears from the process screen and then if I try to execute the program again... same prpblem of the .exe dissapearing, its like nothing is happening or another program is shutting it down when I try to start it!
*** The funny thing is, it was working on wednesday (Today is friday) and after leaving my computer for a day, it doesn't work anymore. My kid was playing around with my computer the day I was away but he is harmless and just plays a football game, he doesn't even know vice city is installed on my computer, but I doubt he did any harm to my computer at all, (ie: trojans/viruses) I even checked my norton, and did a full scan, no errors or viruses.

Winxp Pro
sufficiant memory/space

What i've done: Reinstalled the game serveral times, the typical resetting of the computer, I tried download the crack from serveral websites, same result.


Help me out guys!
thanks in advance.
