Ok - To followup, I was running firmware?Version 1.000.0025 on all the panels which was released back in June or July if I remember. ?They recently released?Version 1.000.0038. ?One of the bugs fixed: "Corrected issue where some larger Smart Graphics projects would fail to load". ?Dont know if that specific bug did it, but all panels were running same firmware and they all locked up at around the same period of time.
Took a little bit of TLC (I had to Recover 1 panel, and a few more needed a couple of reboots). ?I was able to get most of the panels with the newest firmware up and runing again. ?One is being replaced by Crestron as it wont go into recovery mode. ?I spent most of the day getting them back online, but it least Im back up and running. ?
