Could someone please enlighten a very confused new owner of a HI-MD MZ.RH1? I have recorded my class playing their own songs in school and want to transfer the files to my computer. When I do that it first of all will not convert to WAW format but secondly it does transfer the file but I cannot play it. It keeps giving me the following message: 00002460-2100 "Cannot play this track because its licensing information cannot be found .For more information, contact the source from which you received this track." 0084e0 Why does it do that when it is my own recording? What am I doing wrong? I have looked in the manual and here on the forum but can't seem to find an answer to it. I have just recorded the tracks in school using a small sony minidisc microphone and not done anything to them but plugged in the MD into my computer. I have tried both Sonice stage 3.4 and Sonic stage 4.3 but I get the same result. What should I do? I want to play the files and the convert them to mp3. Help please!
