I'm trying to upgrade my MP7 from OS version 1.0.1 to 2.2.6. E-Loader is telling me that no valid midi devices have been detected. The grid player thing works, so I know my laptop is connected correctly. I read that I need to use commandprep 1.0.dli file first, but that's not making a difference.
I'm using an old HP Thinkpad Pentium 4 with Windows XP, USB to MIDI connector.
Any ideas?
