Hello
Just found this thread about Multibridge SD firmware update…we have the same Problem.
Used the MB for some years succesfully, then systemchange and the old paused for 1/2 year. Now tried to activate the old system (as it was and as it worked before, Osx 10.4.11 on G5, Decklink 6.8.1, Multibridge utility 5.5.1)and MB asked for the firmware upgrade..upgrade did not work.
I will be happy, if ther will be a solution for it.
Thanks a lot
Harald
