I have a problem on Windows 8. Mathematica 8 worked just fine on Windows 8 Trial. I have upgraded to Windows 8 RTM and installed Mathematica 8 again. However, Mathematica won't launch. Kernel works just fine. However, graphical interface does not appear. I can see that it is running in the background through Task Manager but no CPU usage what-so-ever. Has anyone experienced anything like this?
I would appreciate any help you can come up with.
Thank you very much in advance.
