[Resolved]When I go into Unity3D (not Pro), there's only a black screen. How do I fix this?

EDIT: I fixed the problem by removing WindowFX(by Stardock).

When I start Unity3D into my new project(with nothing.), nothing shows up in the windows. The “Welcome To Unity” windows is there, but nothing shows up as well. Just the color black shows up. All what shows is a menu. That’s it.
Here’s a picture.

Seeing as you can still see the menu, try going Window → Layouts → Default (or any of the other choices, for that matter).

Did Unity used to work on this machine? Have you done anything that might have caused it to get upset? (graphics card drivers updated? That sort of thing?)
