Apologies if this is one of the questions every newbie has I have reached out to techsupport but have not heard back. I received this DP-008EX Ditial MultiTrack Recorder as a gift 3 years ago. It has stayed unused in the box. I finally work up the nerve to record some new music, read the instructions and turn it on and get this error message! "Mount Error: 01 Please PWR Off" I have tried to turn the power off and restart, the instructions offer no other advice but Im hoping someone here can! Thank you!
