Save problem

[bowen192]

I am getting the following when I try to save certain models:

Shortly after the program crashes and  I lose my work.

I am also getting the same message, more or less, when I try to open some files, but only some of the time.

I am sorry to let you know that there is no such kind of repaire tool. We are investigating this issue and try to get it solved in future release.
