Problem with the editors.

[Mine Turtle]

PROBLEM X:






I have an issue with the editors.


When i open f.ex the level editor, everything is fine, but when i try to add a material, by clicking the decals tab and the ''...'', the editor crashes, and gives me a blackbox error. this isnt only in the level editor, its in every editor. model, particle, material, whatever; all crashing when i click the ''...'' under the materials tab. this has happened every time i try.

if anyone has any advice on how to fix this, please let me know

cheers.
