When you click off "Access CS Live" in Premiere CS5 the error don't come back. When you re-open "Window/Extensions/Access CS Live" the error is coming up again. So, don't use Access CS Live.
Today I mailed this bug to Adobe Netherlands. I will wait a few days and if they don't come with an answer, I wil also mail this error to Adobe USA.
Can you let me know if this solution works?
