My Rhino 6 trial stopped responded when I tried to move a part. I had saved the file right before I moved the part. I waited for like 30 mins and when I saw it still did not respond I force closed my computer and opened it again. However, when I tried to open the file again it gave me this error I attached below. When I close the error window the file looks empty, without layers, parts, not even a default layer, nothing. However, the file still appears to be 21MB. I opened the backup file but it was not the version I had saved before, even though the update time is correct it showed me the version that was 1 hour before. Why is the program giving me this error, and how can I get my latest version back?
