What version of the product are you using? On what operating system?
Windows 7 x64. Gallio 3.2 427 x64

The same error will appear when I try to add a file.

This happens to me very regularly. I believe it is because the dropdown in Test 
Explorer is not set to anything. If you drop it down and select Namespace, then 
reload your tests, everything should be fine.

Another thing that seems to work is to delete all of your settings under 
AppData.
