I recently joined the F@h community a couple weeks ago. I decided to dust off an old Windows Vista PC (Dell XPS 435mt) to add to the folding my laptop does. It works well enough, but whenever I try to open Advanced Control, all I see is this error message:

I've been getting this message with 7.5.1, so I tried downloading the new 7.6.9 release today, but it still shows up. I've tried restarting/uninstalling and reinstalling F@h a bunch as well. I was wondering if any of you have any idea how to fix this? Web control works fine, but I'd really like if I could open up advanced control. I've also tried googling, but I didn't find any working solutions.
Below are some specs of the PC:
CPU: Intel Core i7-920
GPU: ATI Radeon 4670 (doesn't show up in the folding client)
OS: Windows Vista 64bit SP2
Thanks in advance!
