Simple Editor Error
 

I have recently purchased ToW2 Kursk and was wondering if anyone has had the same problem with the simple editor:

Whenever I try to run it it gives me this error: The type initialised for
'missioneditor.rendercolorscheme' threw an exception.

The game runs perfect the only thing wich Isn0t working is the simple editor.

I am running windows 7 64bits

AMD Phenom X4 3.0 Ghz
4 gigs of ram DDR3
Hd6870 1gig
