hey,
I've been happily using 3ds max 7 to make maps and I've been getting decent at it. Blitzkrieg has been giving me no trouble and working fine. I've recently tried to make changes to one of my maps bsps and blitzkrieg crashed max while I was trying to export. I'm fairly sure that It's my map not the program because I just tried exporting the tutorial map and it works perfectly. Help or comments appreciated, thank you.

PS. every thing is textured and their are zero open edges, I'm sure of that. I have portals in the map but I didn't make many changes to the working version of them. When it crashes it just gives me a message saying it needs to shut down and then I get the discreet error reporting thing.
