BB 8820 and 10.4.9 - the missing sync worked like a charm during my 14 day trial period, just bought the paid version and for two days excellent.

Today - got an error message that reads can't connect to device. When I connect usb and start the missing sync, the media card mounts on my desktop correctly, and i then instruct it to sync music....spins, spins and pops up error message.

I might add had turned on password protection for BB yesterday and when connected, was asked for password....it kept on saying incorrect (???) so I ejected media card, shut down missing sync, disabled password on the BB and then started all over....that's when error message came on.

Any idea why this is happening?
