Premiere Pro Cuts Out After 10 Minutes

I am working on a big project and I need my reliable Premiere Pro, but after the first ten minutes, all I can see is the background of the workspace. The 'Edit' and other tabs at the top works, and I can save, but I can't see anything else.There's a screenshot of what happens. This wouldn't bother me if I had an Adobe-compatible computer instead of a cheap Web-Browsing-compatible computer. It is important to note that I reinstalled the program 2 months before, although I had used it before now.
