MP3tag has stopped reading some tags.
Here is the explorer view and the MP3tag view.
If I take an untagged MP3 and enter the tag using Windows 7
MP3tag also 'seems to knows' there are tags there because it will not write to the files unless the tags are cleared first.
Windows 7 pro, SP1 64 bit
Mpeg Options are
Read ID3v1 ID3v2 APE
Write ID3v2 - ID3v2.3 ISO-8859-1
Remove IDv31 APE
If I clear the tags then I can write them and MP3tag can read them
