This means that it's having problems interfacing with the download/proxy service. Things to try:
1) If you know where the services are listed, look for the 'VMC NetFlix Download Manager' service and attempt to start it manually, then try again.
2) Reboot PC and try again.
3) Turn off UAC, reboot PC and try again.
4) Uninstall and reinstall vmcNetFlix app - making sure the user account has admin privliges.
5) Uninstall and reinstall vmcNetFlix app - turning off UAC first.
Let me know what you find out,
