Well, I got it up and running, but its not working correctly. I've got the game running (v20), but host manager keeps screaming to be in host only - which I am. On my big computer, it gives me some other kind of runtime error. So, it looks like Host Manager is not an option for me. I'll have to weed out the maps, put in on cycle and hope for the best. No Height Explode or any other extras.
I also can't find the game on my network to join on server on LAN. I'm tired. I'll try to find some time later this weekend.
