What operating system are you using?

Both games have issues with Win 7 and I believe Win Vista as well. Those games requires Windows XP in order to run.

If you're OS is Win 7 or Vista have it run on compatibility. I had that game before running both part 1 and 2 on Vista and Win 7 with no issue at all.
