Draftsight 2015 closes when launching

I recently upgraded my workstation from a Dell using an XP Pro platform running DS2014 with no issues to a Lenovo with Windows 7 Pro.  I ended up having to download DS 2015 and have had a real problem getting the thing to start properly.  It closes down as it begins to start up.  I have tried uninstalling and reinstalling a couple times with no luck.   Is there any way of getting a hold of DS2014.
