Stumped by a 4-inch piece of plastic.

OK, got a problem here. I recently wanted to play KOTOR 2 again and re-installed it. Worked fine b4 I patched it. Ran the patch, now I CAN'T EVEN READ THE CD. My player runs other cd's/dvd's just fine, and the KOTOR2 disc works on other comps.....just not on mine. My computer has NOT changed since the last time I played through: I meet all the recommended stats. When i try to run the game, or just put the disc in the drive, it ACTS like it's trying to read the disc, and does that for about 60 seconds, then it tells me that I have the wrong disc in the drive. When i just put the cd in the drive, hoping to get an autorun, it does the same thing. When it gets done trying to read the disc, it acts like there's nothing in there. When I attempt an un-install, it tells me that it can't find the setup file. HELP ME!!!!

Trying reverting to a system restore point before you installed the patch.

OK, I'll give it a try. A friend told me it could be some sort of registry thing too. Whatever that means.
