I have a large worksheet that was converted from 15.
Today I made a number of corrections to some of the assumptions that new data has clarified.
When I try to save the file, I'm getting this error:
similar to the error I receive when I'm trying to open a Prime 3 file...
the information in the log file is uninspiring.
here's an extract:
Exception data:

I am going to try a line by line check between the current saved file & the modified version, but it is a mammoth task and since I don't know what I'm looking for I don't hold much hope for success.
Has anyone seen anything like this or any suggestions how to preserve the changes that I've made?
Thanks
Andy
