I recently upgraded to R5F27, but don't think this has to do with the upgrade.

I'm not sure what happened, but after a failed attempt to archive some files (apparently a bad mpeg file), and an attempt to clean out the temporary files in /myth/tmp/work, Mytharchive doesn't work. It will let me run through the steps on the GUI, and then the progress screen shows nothing coming through. I logged into the box to try to look at some logs, and noticed that the /myth/archive directory is completely empty.

Is there a way to just reinstall just this plugin? Should I just do another reinstall (does it work to go from R527 to the same) or is there some better method?

See the hints, under Known Change 7.4

Thank you for the reply, but the problem was completely unrelated, and I suppose it's normal for "/myth/archive" to be empty.

The problem is that somehow "motion" was activated (I'm guessing the cats stepped on the keyboard by the TV) and it filled up all the inodes of the /myth partition with a ridiculous number of files in /myth/motion (I had to use xargs to remove them), so no temp files could be created in /myth/tmp. Took me far too long to work that out, so I feel like a linux novice again.
