hi, i recently received a problem adding songs to my MZ-N510 TYPE-S, before when i added songs, they wouldn't playback on the MD, it was just didnt play any sound. i then installed sonicstage 3.4 and initilized my disc and it started working again, but after i put on a maximum of 11 tracks the problem returned. any tips? i took a big gamble of deleting my best minidisc to add what i wanted.
