Further experimentation:
It used to be that when I put a TV show in a monitored folder, TV Rename would detect it, rename it and move it off the computer onto the NAS where all other video files live.
Now, it does detect when a file is put in the folder and it appears to scan, but in the end it doesn't do anything.
If I go into "schedule" and right click on a show that TV Rename says is missing (from the NAS, but it is sitting in the monitored folder) and I choose "Quick Scan" I get a list where it shows all the episodes. They all have tick marks next to them, including the one that hasn't yet been moved to the NAS. The ones already on the NAS have a green, downward pointing arrow. The one missing from the NAS has an icon looking like a sheet of paper. If I click on Do Checked, it does what it is supposed to do and moves the files to the NAS.
I've done updates as they become available and have not changed any settings.
Let me know if any more info might help.
