Blue Screen When Running Any Version of SOAPUI

I was able to correct my issue by deleting the default SOAPUI projects. I found this link where the user had a similar issue.

I've been using SOAPUI for a # of years now. Recently, when starting SOAPUI, my machine (Windows 7) will basically come to a halt. I am not able to restart my machine and have to power down via the power button and restart the machine. When I power down the machine, I get the Windows "blue screen of death".

I've tried different versions including the most recent version which I downloaded today (5/5/2015). I uninstalled 2 older versions I had on my machine prior to installing this new version.

This does not happen with any other applications.

I appreciate any ideas.

Thanks.
