Unable to backup controller

Hi I’m trying to do a firmware update but before I can do this I want to back up my MC6 - the editor hangs when I try this. It appears to start a backup then just hangs and does nothing.

I tried downloading the editor but the same thing happens. I disconnected the controller, restarted everything but I still cant back it up.

Try a different USB cable (or try 5 pin midi if you’re using USB or vice versa). Try restarting your computer.

what firmware version is the controller running? and also what editor version (shown at the bottom of the editor)?
