monitor mode ULM
means that you are running in User Level Mode and thus Workstation cannot use VMware's hypervisor, but instead it has to go through the Hypervisor API that Microsoft provides.

I have had a lot of problems with Holdem Manager lately so I eventually uninstalled it [and deleted the RVG directory] and downloaded the original install and the 1.09 Beta 29 update as per instructions in several threads on this forum. Now, when I attempt to run the program [as administrator] I receive the following error message:Xenocode Virtual Appliance Runtime \==========================
There has been an error starting this virtual appliance. Error code 0x00Z2.

I am running Vista Home Premium 64-bit and UAC is turned off.
Thanks for any assistance...
