Hi everybody I just got a new MZ N10 recently and i'm having trouble checking out tracks. The software works fine. I followed all the steps in the manual, and the sonicstage tells me that everything has been checked out... however, when i try to play the tracks from the MD, there's no sound... the timer runs, but very, very slowly (like after ten seconds have passed, the timer only reads 00:00:02) and theres no sound. Also, when i eject the disc and insert it again, then everything gets erased and i get the Blankdisc message again... also, i can't check the tracks back in (before ejecting the disc and making it go blank). Sonicstage tells me that the check in failed. I tried to check out tracks from my friend's computer (who uses OpenMG Jukebox 2.2) and it still does the exact same thing, so it's not a problem with the software... Is my player faulty?
