"There are no solution or project files in this location. Please select a different location"

Sorry,

It seems that my solution was named 'test' and I added it to repository as
MODULE 'TEST', so the plug-in silently created MODULE 'TEST\test', and
checking out module 'TEST' caused such error ...
Those are details, of course, but made me scared that something doesn't
work.

This message is displayed after I add a solution to source control and try
to check out it to another location. Usually it helps to repeat check-out
operation ( by just clicking 'OK' again ), but finally I got a project,
which I can't check-out in any way .... Module is ok, but I can't check it
out. What should I do ?

PS.
When I create MFC application in VisualStudio Wizard in creates Resource.h,
I add it to a source control, and next start to edit resources by let's say
adding a new button to the dialog, when I save the project 'Resource.h' is
renamed to 'resource.h', which confuses a VCS a bit it starts to display
strange errors when commiting that file back to the repository.
