I am trying to install x-plane demo to make sure it will run before purchasing the full version. I am running it on Vista 32bit dedicated machine with 4GB RAM and have changed my virtual memory to the /3GB. When loading, the load screen stays on loading the Cessna 172 and appears to be loading (the bar moves back and forth a little) but never loads (I left it over night in one attempt.) It gets stuck in the same spot each time and have reinstalled several times. I have also tried it on my Windows 7 machine and it gets stuck in the same manner but on a different file. I have installed x-plane 9 demo and it works fine.
I have turned off video card panels and updated the card drivers as well.
