You installed Mavericks later than ID. So this goes to Apple, not Adobe.
Because there is already an active thread (referenced above), I'm locking this thread.
Agreed…and the bigger the upgrade the more the risk.
Since Apple is allowing free upgrades from as far back as Snow Leopard and everything was fine before the upgrade, I will fall back to my advice to do a clean install of the O/S after backing everything up.
That said, you may benefit from simply uninstalling and reinstalling.
Me? Mountain Lion is just fine for now but I've already created a boot disk for Mavericks and will do a clean install once all of my software has been declared Mavericks ready. Still waiting for Extensis to update Suitcase Fusion 5.
