Rhino crashing/ saving the file only as Rhino Backup model

Rhino Rhino for Windows
1

Hi, I just did bootcamp on my mac with windows 7 and uploaded rhino 5 with neon and brazil, but everytime I try to work, it saves only as a rhinobackup file before crashing on the next save. I’ve never had this occurance on my last bootcamped mac.

Also, because I just loaded windows 7, its making me do around 150 installs everytime I restart the computer…

Hi Andrews - do you have the most recent Service Release of Rhino, and all Windows updates?

Just loaded the recent Service release and its still freezing, but now its keeping the 3DM files instead of turning them into backup files
