Level Editor Crashes when loading "Lamp" enitites

[Khorne on the cob]

Right, I've tried to load it up on a different map, Rainy Hall to be exact. and it still crashed. Although i can move and work with lamp entities, I just cannot load them from the entity list it seems.

I will post the info Black box has given me:

it says "LevelEditor.exe caused an EXCEPTION_ACCESS_VIOLATION in module MSVCP71.dll at 001B:7C3AF4C6

std:Basic_string<char_traits<char> ,std:allocator<char>
