I've got a similar problem in fact I just bought my MZ-RH910 and tried to transfer my live recording to my SS Library an error pop up "interal error" only about 30+% transfer then stop. I changed my USB cable and tried it again then the message pop up something like license and I clicked OK. It didn't look SS transfer my file but I found out later that there is a file in my pc (not shown in my library) that I can't play since is asking a license The worse thing I can not play and read the original track from my Hi-MD disk anymore. I lost my recording! Please Help
