TGB lost resources/tilemaps

I recently ran into a problem where Torque dropped all my resources from the editor. I had just spent the last hour or two working on a level, but when I went to play it my character was falling through black, empty space. When I got back to the editor, everything was gone.

Not only that, but when I loaded my project from a backup, it was having similar problems.

For one, in the editor, both my character and my test enemy were out of place. Also, my test enemy was somehow a stack of 6 copies. When I played my game, same issue. Just falling through empty black space. Even if I put my enemy right next to me, I never seen him in the actual game. I did see the briefest flash of a fireball that he throws.

Also, when I create a simplistic tilemap just to test the problem, it literally deletes all the information contained within as soon as I save.

I don't understand what is going on, but it seems to be deeper than just my project.

Going to reinstall Torque and see if the problems persist. Anyone know what might cause these issues so I can avoid them in the future?
