STAAD Crashing

I installed the latest version of STAAD.Pro ( earlier this week and have already experienced at least 4 crashes. Two gave me the opportunity to send a report. One just shut STAAD down with no warning. The other one shut down the Analysis Output with no warning but STAAD still thought it was open because I couldn't reopen it. This is very frustrating. Is anyone else experiencing this?

Oh, and no, I wasn't doing anything unusual. And yes, I'm using my local hard drive for the input file.
