ok I installed it, had the files in the live show tagger, hit update files and got Could not load info (Unsupported file format) from:
"D:\oldd\wsp1991-02-09\wsp1991-02-09.sbd.flac16\wsp1991-02-09.txt"
huh?
If this is an older show where the txt file and flac naming aren't really to etree standards there could be a couple things going on. However I would simply start by renaming the .txt file as wsp1991-02-09.
info, as that can be a hangup for it.
Also to strip any old metadata/tag info you should be able to : highlight files - right click - choose "properties", that will bring up the manual meta/tag editing page where you can delete (or add) older information.
