Wasn't sure where to put this, but here goes anyway. I found a way to run MoO under XP
If the game window displays an error then closes immediatly, watch it. It SHOULD say something like it needs "at least 1024kb of expanded memory". What you do, is go to Properties, then Memory, and change Expanded(EMS) memory to 1024. This allows it to run under XP
And if something else is wrong, then sorry. That's the only error I got, and now I can run it normally.
