In Windows Explorer, navigate to the folder where the files where originally located (before they were moved/renamed)
Right click in the folder and access your Repo browser from the Subversion menu.
Drag and drop the original files from the Repo back into your project folder.
In Visual Studio, open "Working Copy Explorer" and navigate to the directory where you just dragged and dropped the files.
You should see red "x"s next to the name of the files indicating that they have been deleted.
Select all the files and right-click on then, then choose "Add to Pending Changes"
After that you should be able to commit your changes.
