The "Too Many Activations" can probably be handled by contacting Adobe Customer Support (not Technical Support).
For digital editions, I have no idea what the allowed number of Activations would be, but it appears that you have exceeded that number.
No proper support for ADE activations (such as a web page where you can view/edit).
You need to contact Live Chat http://www.adobe.com/support/chat/ivrchat.html who will reset ALL your activations.
You then need to reactivate the devices you still use (up to 6).
