I have had FW CS 5.5. for ages on my mac and never had a problem. I am using Mavericks.
Suddenly it started crashing every time I try to open e.g. the Align panel or the Add arrow heads window, no matter if I am editing a newly created PNG or an old one.
The crash report says

So it seems to me there is some kind of a problem with Flash player (I noticed that the panels are actually small swfs in the Fireworks folder).
I tried uninstalling Flash player and the whole CS 5.5. suite from my machine and reinstalling everything but it didn't help.
Does anyone have an idea how to fix this?
