So you're already quitting on this? Didn't expect that. The errors that these people are getting are not because of the game, they are because of their CRAPPY computers. This should work on ANY Windows XP and up, just install Direct X 10, it's FREE. If you want give me the server and I'll try to keep it up and updated for you (if you are gonna go to a different program). I found a pretty cool MMORPG Maker (free) called Genesis (Genesis2D v2.3 Official Download)
And there is always Xtremeworlds if you want a different |Free| program.
