Well, I installed the same update (10.2.8) and this is what happened.

My Itunes and Quicktime icons in the dock turned to folders.
I could not drag and drop anything.

So I ran a program called Dragster that says it may fix this exact problem. No Luck.

Instead, now all my icons everywhere are either folders or some other little pencil icon and it seems that file associations don't work anymore.

I'm looking everywhere for a solution, but no luck so far.
