Robuck: A VXD is a Virtual Device Driver, and VMM is the Virtual Memory Manager. This should give you at least a clue as to what to be looking for.
If you have a VMM error in a VXD, then you have a memory conflict. Next step? Look inside your device manager for all the memory ranges being used, and see if there is a duplicate. If you find a duplicate, pick the item (device) that you installed MOST RECENTLY and uninstall it, right down to the registry keys (if any). Then re-install it. If you still get this error, go to the vendor's site and see if there are any driver, firmware (if a hardware conflict) or other updates available. Install the updates and reboot. Do you still get the error?
Hope this helps.
