I was running CALM with no problems, (windows 10, with my libraries on an ssd external drive - not networked) and then after a short span of non use (and updating calibre), when I run calm the resulting library is empty.
CALM works on calibre 6.14 (both installed and portable) with all the relevant information, but not on higher versions.
Also when I used the tag updater, I got the following error message about columns and all the tags disappeared from the library. I got round that by creating new libraries and moving the books over. Then I had no problems.
After adding a few books and realigning a couple of columns I am back to the error message. I have not added or removed any columns.
I have calm installed on a 6.14 portable version and am able to view everything but cannot update the tags.
Edit:
I got around the empty calm library by using the portable version meta folder, but still getting the error about columns.
Any help appreciated
