I am running it in compatibility mode for Windows XP [service Pack 3]
I am using 64x Windows 8.0
If I try to load a saved custom map (one made with the map creator), or one that I generated using the in-game ability. Upon hitting Preview or Load: the game pulls up the normal [Please Wait: Loading] bar, but once it gets to about half, the game simply closes out, and a few minutes later I get an error message saying the main executable for the game has stopped running unexpectedly.
