V. 3.29 Introduced Microsoft Media Player Errors For Me

[LyricsLover]

Similar reports suggest that a cover picture that is too large may be one of the possible causes.

Saving changes in flac files songs don't play

Usually I use mp3tag to add cover art to my media. Today I used the newest version 3.29 and when saving the alterations, the files no longer play. Also the file information on 'Title', 'Artist' etc. disappeared in the windows explorer. I wish v3.28 was still downloadable.

Could you please check the size of the cover art embedded in your FLAC files?
