Unable to delete TBK file, Error #0

Are you suddenly getting a strange error message telling you the program is "unable to delete" a TBK file for a screenplay I'm working on. "Error #0" I click "ok," but the error keeps returning every couple of minutes.

The cause is probably that your Timed Backup folder is set incorrectly and is pointing into a folder where you do NOT have write permissions.  Below is an example of an INCORRECTLY set folder path:

 Normally, you want these paths to point to the "Screenwriter Documents" folder located in your user's Documents folder.

Also, the Timed Backup folder usually points to the Timed Backups folder WITHIN the "Screenwriter Documents" folder.

Once you make that correction, you will no longer get an error.
