Ok, thanks for you help... I realised it happens to both Fallout 1 AND 2... I can install them, play them usually once and when I try the second time I get that error... I have to then re-install the game and play again, re-install, etc. I've checked my Computer for virus', but haven't found...
Alright, thanks guys, and I checkout out Ian-Out, it's looking good!
And ColJack - Yeah, I understand what you mean, seems a little difficult just for some minor changes.. I just wanted the interface and such, but yeah thanks for the help
