nstalled ow projectsNsight Visual Studio Edition 4.0 RC1, now VS2013 won't sh

Complained first about corrupted file, “ActivityLog.xml”
The start page won’t load content.
If I Open an existing project, nothing shows in the solution explorer.

This broke VS2013

Uninstalled the RC1. Went back to the restore point created when I started the install. No joy.

How can I fix this?
