I bought the game Painkiller. I install it and get ready to play. Everything starts up fine, except that the flash screen as Painkiller starts is the screen for the game Uru - Ages Beyond Myst. I play for a while, having fun fragging. Then, I restart my computer, and Painkiller will no longer load. I just get a Uru splash screen and then an error message saying the application failed to initialize. I re-installed, and got the same thing. To thicken the plot, my file-type associations and grouping in My Computer is gone, plus my Processor is no longer listed when i load up System Properties. Can somebody tell me whats going on here! Thanks in advance.
