I have a campus license version of Mathematica installed on my Win7 64 laptop, Worked great. About a month later it stopped working, although I can still run a kernal session no problem so it doesn't seem to be a licensing issue. When I try to start the front end I get an hourglass for about 5 seconds, then it goes back to a regular cursor as if nothing happened. Except, the fan goes on high and a look at the task manager shows that one Mathematica.exe 124k process is running, and worse a second Mathematica.exe*32 1,460k process is running that is taking 25% of my CPU (a logical quad core, so it's fully occupying the core its on). (I thought I installed the 64 bit version). I tried rebooting, uninstalling, rebooting, reinstall, rebooting...but nothing works. Probably related: I use Chrome as my browser. When going to a cdf presentation, like on Wolfram Demonstrations, the cdf won't load and I get a popup that says "Choose MathLink program". I can make things work correctly by choosing the Mathematica kernal...but it's pretty weird it doesn't know where to go by itself. Any thoughts? I've tried everything I can think of. 200G of hard drive available and 8G RAM. I have a switchable video system (mobo Intel vs. Radeon) and same behavior regardless of the active driver - and regardless, it worked when I first installed it a few months ago.
