I too am having a problem with the Spider Jam (2.09) rebooting down every time I turn the dial in order to view my WAV audio files on my 2 GB SD card. I have tried everything I can think of and spent hours upon hours researching this problem, all to no avail. I have formatted the card via the Spider Jam and then reformatted to the F16 format (or whatever it is) via my Mac desktop. I haven't read a resolution from Line 6 anywhere. According to other internet postings, this seems to be a significant issue to many Spider Jams. Please help.
