I am using Windows 7 x64. As I understand the problem in graphics settings/drivers or Desktop settings. Tried many suggestions (e.g. changing windows theme to Default, compatibility with XP, Vista, 2000 etc.) but it does not help. I have Nvidia video card if it matters. Hope for your help...

Who knows? So have I but mine works fine. Like the FAQ says it could be so complex that no one except the Mathworks will be able to figure it out. They can actually set up a webex session and drive your computer if they need to, to help you get it running again. We can't do that.
