I searched but only saw one other thread involving this error message. I have restarted my PC (twice), reinstalled Calibre (also twice), and tried running it w/o any other programs (although none of said programs have anything to do with cleaning/deleting temp files as far as I am aware).

I have rec'd this error message both when attempting to move files from one library to another and when trying to alter metadata en mass.

Here is the latest version of said error message:

What did I mess up? How do I fix it if it is fixable? (Would be awesome if it was fixable without losing all of my settings/plugin settings *again*)

Thank you in advance!
