Did you ever find a solution to this problem?
I have exactly the same long list of errors and it's driving me bonkers.
Also on a mac, using cs5.5, tried a whole bunch of stuff which hasn't worked.
No solution yet. Shorly after I posted my message about that, I left on a 4 week overseas trip - I'm still on that and a bit out of touch with things.
I get back to the real world on July 24 - and if I discover a solution, I'll certainly let you know.
