Please let me know if there are any known issues like this and/or any solutions or evaluations to help determine the issue and "fix" the file.
There is a .jmp file I have been using since ≈2016. Last Thursday I worked on the file without issue (that I was aware of). This morning I could not open the file. The message I get is shown below along with the SW and some system info. The file is in a network folder. There are other .jmp files that can be opened. There are over 15k rows of data and may columns of data. There are also many columns for evaluation that I created to help sort and process the data so I am really hoping to recover the file. Do to the content, I am not adding the file.
