I agree... great game. Dug it out recently and thought I'd give it a replay, but got the same error. I'm not sure if Acclaim has a working XP patch out or not... but one thing you could try, (as a last resort), is to re-install 98, then XP and set up for a dual boot. You'll have to make sure that you partition at least some small space of your hard drive to FAT32. Good game or no, it's not worth the effort as far as I'm concerned. But, my roomate set his pc up this way when he first put it together, and as a result, can play a lot of these older games trouble free.
