Hey Guys. I was just reading your thread and i have a similar problem.
I just updated my tower to Leparod and my final cut would load up and just crash before getting past the load screen. So i deleted my prefrences and got a little bit further.
As soon as i tried to load a setup that involved my AJA Kona card it would crash again.
I then tried to get into my AJA Kona Control panel and it would also crash.
So i just tried to get to my Expansion Slot Utility app. and there is a big circle with a line through it saying that it is not supported on this architecture.
What can i do to get up and editing again???
Thanks in advance
Rob
