I was gettin' the error I posted earlier and I'm runnin' Windows Xp Pro NOT Windows 98 and also runnin' 2 gigs of ram in my system when I received that error too .
The MFM I was wantin' to run was just to memory hungry and my system would crash ... took awhile to figure that out too and I got that information from the folks here ... my game ran smooth as well until that mod was installed and then after I un-installed it I would still get a CTD.
So , I had to un-install and go into registry and straighten that out and now all's well
