ETX90 update failed - now the autostar won't work

Hi all,
I tried to update my Autostar last night, but the serial cable got knocked
out during the update cycle (at about 7%), got a message on the screen to
power cycle the scope, but now it won't respond to any communications.

Anyone got any good ideas about how to get the autostar talking again, or do
I need to send to Meade or similar for a repair?

Thanks for any help

Rob
