I have the same problem in both Windows XP and Windows Vista.
"
Access violation at address 00401BBD in module 'hulugrabber.exe'. Read of address 0000004C."
I tried to change DEP settings
(Control Panel -> System -> Advanced -> Performance -> Settings)
from "Essential windows programs and services only"
to
"All programs and services except those I select".
And turned off DEP for
Hulu Grabber,
MTV Grabber,
ComedyCentral Grabber,
CBS Grabber to no avail
