I'm using it right now. No luck.
I'm using these files to find my source on Discogs: /t/1992/1
The ones that don't work are 'Search by Album', 'Search by Artist', and 'Search by Artist + Title' (and probably 'Search by Extended Release ID').
The problem only started a few days ago, I'm not sure why. The 'Search by Album' option is the most useful to me so if there's an alternative or if you know what's wrong, then I'll greatly appreciate your help.
