Level Editor Crashes

[WASD]

I posted this in the mods thread, but now that I think about it, that probably wasn't the right place to post it, so here's my problem. I am running a copy of Amnesia from steam, and the level editor is from Frictional Games's website. I use Windows XP and have a Nvidia 9500 GT, along with an Intel E8400 3.0ghz cpu. It seems from the screen that the editor attempts to update before quickly giving me the message"LevelEditor.exe cause an EXCEPTION_ACCESS_VIOLATION in module nvoglnt.dll at 001B:69591240" Thanks for the help!
