Hey @Slak_Jaw Thank you very much for all your asistance. I already found the problem with my files and is the tag format for metadata. I used a program to edit metadata from my files and the tag format originally was vorbis but i changed it to (Vorbis, ID3v2.4.0, ID3v1) so i returned it to vorbis only and already load the .flac files. I am ready to suscribe now cause change the tag format is so easy and fast that change the files to mp3.
