yes i know but i could transfer files on my md till i updated the version and this mini disc walkman i got with my computer and the mini disc drive

Hello everybody. im new here and i have got a big problem at the moment with Sonic Stage. I´ve got a MD Walkman MZ-R501 and a mini-disc drive. After i have updated the version to 3.1. i coulnt transfer my mp3 files to my mini disc anymore. Everytime when the song was 95 % transferred it said . the song cannot be transferred on the md. then i uninstalled the new version and installed the version 1.5 . but now i have got the same problem . at 95 % it always says: The song cant be transferred-Error with the exchange of the key for the coding. i dont know what this could be . does this has got anything to do with my mp3 files with the copyright? i dont know but i bought myself new mds so the problem cannot be old mds. You really would do me a big favour if one of you could solve my problem. i´m really gettin frustrated
