File Manager crash

Hello,

I have recently installed xbmc for the first time and now when I try to add a source folder for my movies the screen goes black and later I get an error message that my video drivers have stopped responding.
I have tried other things and it seems to crash whenever I open some sort of file manager or browser. For example it crashes when I press the get more skins button.

Here is my log: http://pastebin.com/ariF67dW

Thanks in advance,

Makke

Edit: Some additional information:

Windows 7 SP1 64 bit
AMD Phenom 9550
4 GB RAM

XBMC 12 rc2
