Michael,

The problem is occurring on the 2nd computer, too. The file I closed about an hour ago will not open. I double click in the directory, when MOI opens, "Path not found" appears. File Info (Command-I) indicates it is opening with Moi v3.1.app. I reset that and no change.

I tried reducing the file name to one word and that didn't work.

From within the app, I use File>Open and the file opens blank with only the title in the upper right corner.

I got my model transferred to VectorWorks before closing the MOI file.
