Hi all! Windows 7 stopped reading covers that are contained in my MP3 files. After that, I could still see them, but not in new files. After cleaning thumbnails on C: disk, all of them simply disappeared, but are present in MP3 files. Nothing changed in AVI, MP4 etc. files. What could have happened? I have already tried options like 'Always show thumbnails' and 'Always show thumbnails, never icons'.
