Unity 3.x not showing scene properly?

Dear Unity community,

I have toyed around with Unity 2.x, in a very casual manner – enough to be intrigued by its capabilities, so I have a rough idea of how it’s supposed to look. Today, I downloaded and installed Unity 3 and am having some peculiar behavior with it that I’m hoping someone can help me with:

Every time I open a project (either the two sample ones Island Demo or Bootcamp Demo, or one downloaded from Unity’s site), it seems to “convert” the project. I’m guessing from 2.x to 3.x?

After the conversion, Unity 3.x comes up, but the scene is completely blank. I see the widget for the Main Camera, and the little “direction” widget in the upper-right, but that’s it. If I try to “play”, it’s completely blank. I see the various assets, and such.

I’m running on Windows 7 Ultimate 64-bit. If anyone has any ideas on how to get this to work properly, I’d be obliged!

I uninstalled, and did a Registry and disk “wipe” of anything Unity-related. I re-installed with the latest using UnitySetup-3.0.0.exe, and I still get this behavior. Any help would be hugely appreciated!

By “blank”, I mean that the scene is entirely blue when I “play” it.

I tried a “Build and Run”, and that seems to create the game (Bootcamp) just fine. Apparently, it just isn’t displaying properly in the Scene/Game window from the Unity UI, and I can’t quite figure it out.

Interestingly, when it was “building”, I did see a brief flash of content in the Scene window – but then it was gone.

Unity Projects can contain multiple Scenes. When you open open a Project you also have to open a Scene within that Project.
