file unavailable???disk completed???

I have been running into some problems lately and I can't tell if it is because I am not following the instructions correctly or if I am actually running into a system error.

I composed a song in the sequences consisting of approx. 12 tracks and had them all looping between 4 and 12 measures for the default 64 second setting which I saved only as a SNG file on the compact flash. The next time I turned on the keyboard and loaded the SNG, the song only played for 4.4 seconds and I ended up losing the sections of the tracks that had the 12 measure loops. I then tried to access the track edit page and the entire keyboard froze. This was not resolved when I powercycled.

I then recreated the same song using the song template method displayed in the instructional video. After saving -ALL- in media mode I was told FILE UNAVAILABLE when I tried to access the PCG file as well as the SNG file. I then saved just the SNG file and was able to access the tracks but the PCG is still FILE UNAVAILABLE. In some cases when I try to load a song it also reads Disk Completed and will not let me access it.
