I just reinstalled SolidWorks 2010 SP0 after upgrading my OS and reactivated the license.

Now, when I try to open parts/assemblies, the file essentially opens, and I can work with it, but I can't see anything.

The viewing window is frozen.

I've attached two screenshots.

It can't be a computer hardware issue since SolidWorks was working perfectly fine when I only had 4 GB and 32-bit Windows XP.

Now, with 6 GB and 64-bit Windows XP, I get this strange behavior.
