Loadrunner controller crashing at start with "Failed to create empty document."

Hi,

I'm evaluating the trial version of Loadrunner 9.5 (patched to 9.52) but can't seem to create a load scenario.

I've created a simple RDP script using the Virtual user generater, but when i try to create a new scenario in Loadrunner Controller, it crashes after I select that script click OK.

An error message saying "Failed to create empty document." appears, then another msg box appears saying it's crashed and needs to restart.

I'm running LoadRunner in a virtual PC with Win XP SP3. No anti viruses running in the VM.

Is there a patch that i'm missing ?

Thanks
