I have had a ripnas for 10 years and it has suddenly decided to stop retrieving album/song metadata

Disc 1: <no meta data> Reject 1: No Meta Data

This is the error in the results log file, i think I'm running release 13.2 but it's hard to know, definitly 10 years old but it's worked till now

I have seen on the forum that amg needs to be removed from the sources list but cannot find where this is detailed, which exe which program, obviously want to rule this out, please can you help

Have tried with old known cd's, still the same issue

Thank you

p.s. I do not want to upgrade as am not sure that the modern version would be supported and probably not got the IT skills to carry it off.
