Music Box Problems

[NoTTD]

'09 G37x

(1) MusicBox keeps telling me it is full. I went in an deleted several hours of material and it still won;t let me record since it is "full".

(2) When I enter the artist and album info it invariably continues to show "no artist" and connects the artist name to the end of the album info. (i.e., instead of Artist: "David Bowie", and Album: "Changes", I get "Changes/David Bowie" all on the album line.

Any guidance would be appreciated.
