can save file in v20 but not v21

JSLJSL Global Mapper UserPosts: 434Trusted User
I was working with the attached workspace in V21 and got the below error when I tried to save, but when I opened the file in v20, I could work in it and save it without any problem,  Unfortunately, it's too large to attach as a file, but any suggestions would be appreciated:

    Hi JSL,

    If you contact Blue Marble Support directly via email (, they should be able to set up a place for you to post the workspace file to they can take a look at the problem.
