thanks, guys. I gave up because those things looked okay and uninstalled. After I reinstalled it still wouldn't let me run it!
BUT I FOUND THE PROBLEM
ThreatFire, which I recently installed, must have mucked it up. I had it on the normal setting and I didn't get a warning about it needing permission for anything. Even when I suspended it using right-click it still wouldn't work. Immediately after I installed it, I can start a virtual machine. Unfortunately I have to reinstall, though...
