Problem to start the game with the beta patch

[Hotkey 0]

i get the following message diretly after starting with the patch enabled:

"Error compiling vertex shader VSTerrain".

I've installed on Vista 64 bit and tried to start also on Windows XP. I'll now try to install again on XP, maybe it is/was a UAC problem on vista.

System is GF 7900 GTX, MSI Neo8 mainboard on Vista and XP

update Just deleted the folder and reinstalled on XP but no luck, error still persists

p.s. sorry for crosspost, but i guess this forum is the suitable place for those error submits. If not feel free to delete this thread.

Someone else had the same problem (dunno what OS though), which was resolved by starting the beta using the batch file provided.
