Hi, i have a big problem,
The installation of the game is ok, i execute the game, load the map, i move in ghost mode around the map but just when i click on play (or press any key to play) the game crashes and it goes out to desktop. I played demo on same PC and all was ok. Is anyone having the same problem? if so, is there any solution to fix it?

Thanks

Edit:
My PC specifications are:

Intel Pentium Dual core 1,86 GHz
GForce 8800 GTS (320mb)
1GB Ram
