Recently I'm not able to go back and play old clips in the stored folder. It tells me "Sorry, the file could not be found".

Blue Iris version 5.5.1.12

New recordings are saved on the local disk up until they are 3 hours old and then moved to the Stored folder, which lives on a NAS. I've actually done the "Delete & Regenerate" on the database and it still shows all my clips, with thumbnails, and the clip storage chart shows the correct colors and space usage. It appears that everything is normal, but it claims files can't be found when trying to play them.

Also, if I delete/destroy a clip, it does get deleted from the NAS.

Any ideas what's going on here? If the files truly can't be found, then the database regenerate should also not be able to find them, but it obviously can.
