0.39.3 doesn't recognize few correct files in the 'Par 2 set' section.
In this case it's a bunch of 22 nfo-files.
MutiPar and QuickPar are recognizing, but current AB will load additional PAR2s to correct.
I stopped downloading and unpacked with "Unrar PAR2 set" <ctrl-U> because I knew unpacking will work.
Maybe this little flaw of dl unnecessary PAR2s can be fixed.
