I am sure you understand I am DESPERATE.
I have just bought a new MZ-NH1, and was uploading several songs on a 1 Gb disc, when SonicStage 2.1 crashed. After that, the MZ-NH1 is not able to recognize it contains a disc or not, and always says "No disc", even with other older working minidiscs.
Nothing more to say. It's 11 pm, the only thing I can do is remove the battery and hope that it is some firmware issue going away with the night. Of course I will need to take it back to the shop... but why me!!! :-(((
