Fences crashes after the 3.1 update

I was prompted this morning to update Fences 3 to the latest version.   After the install and a restart of my PC, fences will not start up.  I get  message after my screen flickers a few times that says:

 

Fences has detected that Explorer was not closed properly.  As a precaution, Fences has been temporarily disabled.

Tore-enable Fences, right click your desktop and choose 'Enable Fences'.

 

I have tried to re-enable, but each time it does the same thing and ends up crashing with the above message.
