Here's the problem.

First, I couldn't run it at all.

Then, after I enabled the Win98 compatibility mode, I got it running until I entered comabt, where it crashed.

Then, for unrelated reasons, I changed my GeForce4 MX 440 to a GeforceFX 5200, and got the game running combat too. Until enemey began moving, where it crashed. So, any ideas where to go from now?
