Unable to use Activiti template for new process

Good morning all,

I've noticed a few problems with using Activiti designer.  I'm using Eclipse Indigo & installed JDK 1.8.0_25 on a Windows 7 laptop.  I am creating a new workflow process & would like to use one of the default workflows as a starting point.  I created a new Kickstart Project & selected File -> new -> Other -> Kickstart Process diagram.  When I "Select the initial content for the new diagram".  I have a selection of default workflows that I can choose.  I selected the "Review & Approve Activiti Process" it throws an error in my error log in Eclipse that says "unhandled event loop exception". I have included the log error below.

Can someone explain why this error is occurring?  with my limited understanding……. I believe NullPointerException errors occur when it is looking for something that doesn't exist.  Is there some problem with my development environment that would cause this ?
