Bleh...I have no idea what I did to cause this!

I started a new level, imported a terrain block, and a collada static object. All was going well till I added a second terrain block, the one that you can do direct from T3D without importing a heightfield. As usual, the textures were completely off, so --as I usually do-- I started clicking the terrain with the terrain painter on to get the textures to correct. That didn't work, so I figured I would just save and see if that helped. Now, whenever I try to load the level it just hangs at the loading screen saying "waiting for server". Waiting for server, wth?? Hell, at this point I cant set up a multi player game to save my life! And no, i don't have the "host" button checked. It hangs no matter if that button is checked or not. All of the stock levels still load up fine. Does anyone know anything I can do to get back into my level or am I left with another bitter lesson about making backups?
