STAAD Foundation Advanced mat analysis crashes when trying to create moment envelope

I have been attempting to analyze a mat foundation and design the slab but have been having issues with either the program crashing when trying to define an envelope or designing the slab itself and not getting results for rebar design.  These issues usually cause the program to crash most of the time.  I am only running 12 load combinations and have 27 column reactions.  I'm attaching the file with the secure ftp site.  Currently using v.8.2.0.31.
