I am having a great deal of trouble as it does not always record. Do I have to leave the USB in when Saving to file for any length of time, as it dies not give a message that Saving is Complete. If I only record for about 10 minutes, the next session of recording does not work. Very frustrating! I definitely need HELP to get the Digitech to work satisfactorily.

You have to leave the USB in for a while to Save the File. It does not let you know when Saving is finished, so to be on the safe side try leaving it in for 30 or 60 minutes depending on how long the recording is.
This just started to happen to me, looking forward to seeing a response.
