Better ask in the Digital Editions forum.
- One is that the connection is being blocked by your firewall. Try turning the firewall off (temporarily) and trying to register again.
- Another is a bug in ADE2. Quite common: but I don't think it is the issue for you. May be worth trying 1.7.2 just in case ...
There are lots of bugs in ADE2.0 (and 2.0.1). Try replacing ADE2.0 with the older but more reliable v1.7.2.
(You can have them both installed at once if you like.)
Version 1.7.2, it is a little difficult to find, available on Adobe site for Windows and for Mac.
The forum software is sometimes corrupting the link above. There shouldn't be a blank in 'editio ns.html'. The following redirects to the same page: http://tinyurl.com/diged172
Tried reinstalling AD 2.0 - same problem
Tried sjpt's suggestions (firewall off, AD1.7.2 installed) - appreciate them! especially the link
Unfortunately I still can't connect to the activation server.
Since jt and I are having problems with the activation server on the same day - wonder if it's a server problem? Very inconvenient; 'll try again in a couple days. Maybe come Monday, someone at Adobe will be paying attention.
Having to deal with ADI to get a library book is a horrendous waste of time.
Looks like the server is back up - 9/29/13 1200 ET. I was able to active the ADE 1.7.2 I installed. Haven't tried 2.0. Yeah Adobe!
