... I play GTA San Andreas... 
Yeah, I hadn't comleted a few last missions (I think) so I started it all over again 'coz I don't have any other to play and I can't let my vacation waste can I?
But I faced a problem. While I can install GTA SA on the both OSes on my PC (2000 & XP) I could start playing it only on 2000. Dunno why, but when I try to play it on XP it gives its normal error of unexpected behaviour thingy and the app had to close, also giving that Debug button. I tried again and again and even tried to run it with compatibility as 2000, but it didn't work. Do you guys know why it works on 2000 and not on XP?
I had recently transformed my XP to look like Vista (a complete transformation pack, changed everything, icons, themes, windows, sounds, stuff). B4 my GTA SA worked perfectly. Could the whole transformation be responsible for this thing?
If you have any ideas please comment them. Would highly appreciate ur help for playing on XP rather than restarting to 2000 whenver I want to play! 
Thanx,
Firoze!
EDIT - My GTA SA works!! 
I had an idea! I went and downloaded a No DVD patch for the game and copied it into the directory of the game and it worked in a jiffy!!! I didn't think it might work! It's amazing that now I'll be able to retain the Vista look and play right on my XP!! What's more, I can now remove the DVD from the drive, and no need to have it everytime I play! Thanx!
