I ran into this problem when I had my MBP hard drive replaced. I openend Fireworks (or any Adobe app) and got a popup that said “Licensing for this product has stopped working.” Contact Adobe Customer Support.

So I did. They freed up the activation, but that didn’t help. That wasn’t the problem.

Soon thereafter I found this page: http://kb2.adobe.com/cps/512/cpsid_51260.html

The first step was the winner for me: deleting /Library/Preferences/FLEXNet Publishing

Hope this helps!
