OG Crashes when opening vss

I download a NetApp stencil set from VisioCafe and when I try to open "NetApp-FAS-Series.vss OG will generate a crash report. For the stencils that I can open they are not displayed correctly.

OG Version: 6.2 (trial)
Stencil: NetApp-FAS-Series.vss
Location: http://www.visiocafe.com/downloads/netapp/NetApp-Current_2015-02-13.zip

Crash Report:

For example, “I tried to drag the framistan onto the hee-whackity, the application didn’t respond for about 10 seconds, and then it crashed. This is the third time it has crashed while I was trying to do the same thing, and it only started happening since I installed CrashDoubler 7.8!”
