Okay, so I did a test model of a sniper about a month ago, and it worked fine, but now I'm trying to do a sword model, and whenever I inject it into darkmatter, it shows up fine, then I add it to the map, then I select the new model, and an unhandled exception occurs in my application, blah blah. I followed this, which worked before. Any ideas? Thanks.
Oh, and when I decided to try the map anyway, it froze (it's a clean map).
