No good I'm afraid,
I have brand new mac mini, clean install of Dreamweaver CC, I am using Design extender 117,
I have destroyed the Dreamweaver config folder, uninstalled databridge and design extender in Extension Manager.
Restarted, re installed just design extender, launched dreamweaver when it proceeded to complete the install, all three phases completed, quit dreamweaver, relaunch and then try to activate and I get the same, maximum number of activations error in red.
Gone back to my downloads, reset all activations, taken a look at the number of activations available for design extender, 2, and tried again.
Don't know what to try now,
