URGENT ! I tried updating my HD300 with the 2.01 flash memory update using Line 6 Monkey. However, an error pops up midway through the update which reads : Code 80009000 Unknown MIDI error. And the main issue is that the display on my HD300 is still stuck on "Downloading..." !!! Now I'm afraid that if I unplug the USB cable, it might render my HD300 unuseable ! Should I try turning off the power on the POD ??
