Edit: I don't know why it happened, but the crashes stopped when I updated to the new version of UDK (2012-02).

Hello! I've come across a crash bug. I've searched for answers for two days straight, but found nothing that has worked. It happens when I move from one level to another with the "open" console command or if I use the "exit" console command. It's strange because I load a level - my main menu, and from there I can start a new game - which loads another level (which uses streaming levels successfully) without problem. The problem arise when I want to go back to my main menu level. Then it crashes. I've built two small test levels that switch back and forth - and those work. But the level with all my work doesn't. Also, if I use the "exit" console command from anywhere (in game menu, main menu, doesn't matter) it crashes as well. I can't seem to "open" levels from the editor, the command just does nothing. But in UDKGame.exe, even when I cook the content and run it from UnrealFrontend.

Here is a Log. Strange thing though - sometimes the log isn't complete - as if the crash just cut's off UDK completely.

System.Runtime.InteropServices.SEHException error in UDK:

Sorry for the Swedish error at the bottom. It says it's an exception error in an external component.

I'm running UDK 2011-11. I'm downloading 2012-02 to try if updating helps.
My system is Windows 7 Home 64bit. Swedish, UAC is off.
Intel Core i7 860 @ 2.8GHZ (8 CPU's)
6GB RAM
with an NVIDIA GeForce GT 220.


If someone can help, it would be very much appreciated. We're on a deadline and on a tight budget - so this is quite a headache (and ulcer) right now.

Thanks in advance!
