Visual Studio with Resharper. Code editing will not respond to keyboard after running Windows System Restore

Question

I ran a windows system restore on my Windows 7 PC Now when I open my visual studio solutions in VS2015 Update1 , when I type into the source code, no changes are accepted.

I can create new projects, and I can open the source files in notepad.

I have tried restarting the computer.

The problem disappears if I uninstall Resharper Ultimate 10, and re-appears if I reinstall it.
