Vasari files crash at re-open quite often

I am trying to teach Vasari Beta 3 in a deign studio setting...the students are getting this message alot..when they go to open their files. Anyone have general advice?

I just gave up on this issue...whats the point of wasting my student's on it. No one form autodesk even reads this forum, hence it is useless....

Vasari is also crashing every time I click OK when I select a weather station. PLEASE HELP!!!!
