Vista - Error when making video call - (0x8100039d)

I am running Windows Live Messenger Version 2009 (Build 14.0.8064.206) on
Windows Vista Business 64-bit. Please advise on how to resolve the following
error when trying to make a video call:

Messenger is not available right now. Please try again later. (0x8100039d)

I am not running McAfee Site Advisor and I have tried the following steps,
as detailed at the following site
(http://messenger-support.spaces.live...3F!15235.entry) in an effort to resolve the issue:
1. Disabled the QoS Packet Scheduler
2. Ensured there were no third-party toolbars installed
3. Disabled IPSec

None of these resolved the issue.
In addition, I have gone to Tools/Audio and Video Setup... and verified that
my webcam is functioning properly.

I appreciate any suggestions or recommendations on resolving this problem

Do you have VMware (or VirtualBox) installed on your machine? On my PC, I

1) disabled the VWware network cnnections VMnet1 and VWnet8
2) disabled the VirtualBox Host-Only Network (may not require)
3) exit and restart Windows Live Messenger.

The video call worked fine afterwards.

Regards,
Ming
