Hi, I just received the TC HELICON HARMONY V60.    Footswitch is working properly when Harmony v60 is turned on.   After a while (1-3 minutes, footswith is freezed and does not work.        If I turn off, and then then turn on the unit, footswitch is working again, but after a while is not working at all again.    Thank you for your assistance.
