I uninstalled BG a few hours ago( a graphics problem i thought would be fixed be reinstall) and every time I try to install it, it freezes at either 15%, 18%, 58%, or 78%. Please help! I won't be able to play ever again!(Until I pay money to get it fixed, and I don't want to do that)

Huh...try to check Register just in case. And try to run the Setup from CD.
My Computer->D:(or whatever)->right click with mouse->explore CD->setup.exe

Try cleaning the disk and/or CDROM drive.

Thx ill try those.

Or if any of that didn't work I suggest this. Go email Bioware and they will give you details of trading in your Disc for another. I believe it's a small fee of 5$. Or you can borrow another disc from a friend. If your friend refuses offer him a trade of another game you haven't played lately. (Not permanatly of course but for a little while) I hope that helps you out.
