New Post: Cannot run python script in windbg

Hello All,
I have a problem with running python script in windbg.
I was able to load extension:
.load pykd.pyd
But I cannot run simple script:
!py c:\scripts\hello.py

Output is: 'script file not found'
I am pretty sure, that scripts exists in added location.
My OS: Windows 7 x86

Any ideas what could be wrong?
