Here are some more ideas to try:

1. Are you using any customized theme or desktop settings? If you are, I'd suggest try resetting all the way to default.

2. Check out the display hardware acceleration slider and move it all the ways to the left just to see if Vue will run.

To do this: right-click the desktop and select properties.
Choose the settings tab
click advnaced button
click advanced tab
There you will find hardware acceleration. Move it to the far left and Apply. Then try running Vue again and see if it works. If it does, then it means your graphics card is conflicting. You can try 'bumping' the hardware accel slider to the right and trying again-- keep doing this process until it starts crashing again. But the real problem, in this case, would be your drivers.

3. Also,consider downloading the free version of Pioneer and trying to install it. If it works and your xStream does not then somehow xStream is misconfigured. Perhaps it's one of the apps which it is supposed to connect to that's the problem? Can you install xStream in isolation mode where it doesn't depend on any other 3D apps? I dunno as I don't have xStream.
