I’ve just started having this problem too. I noticed it first when I installed Magic Bullet Suite – although I’m not certain that MB is the cause of the problem. Before I installed MB I hadn’t used AE for a week or so, so something else could have happened to cause the error. Also, I uninstalled MB and the problem still persisted.
Master Suite CS6
Latest Magic Bullet Suite
Macbook Pro running Lion
Any ideas would be very well received!
