Having some problems with the Splinter Cell: Chaos Theory no-cd patch

[Baulderan]

Alright, before I continue on with this post, I do own the game, I just hate having to lug my CD out every time I want to play. Ok, onto my question:

I downloaded the no-dvd patch from GCW and followed the directions to the point- I copied the files from the System folder in the .rar into my System folder in SC:CT directory, and the same with the Maps.

When I go to boot it from my start menu, however, my mouse turns to an hourglass for a few seconds, and then does nothing. The game doesn't pop up, it doesn't give me an error message... it just does nothing.

Is there something I forgot to do?
