I started having the same problem this week. ADE had worked fine until now. Like you I started by not being able to connect to the fulfillment server. I tried all the fixes, uninstalled, reinstalled, rebooted, nothing worked, couldn't deauthorize my computer so resorted to the control shift d option, that deauthorized, but then I couldn't authorize my computer, got the error could not connect to the activation server. I went through all the uninstalling, reinstalling several times (both ADE 3 & 4), and was getting very frustrated. Finally I went into my admin account, ADE showed authorized there, tried to add a borrowed library book & it told me that I had to authorize, so I clicked on help, deauthorized, then authorized, the book transferred, plugged in my Kobo Glo & added the book to it. When I logged off of my admin account & went back to the account I normally use, my ADE still shows that it isn't authorized & the book I added is not in my library. So I guess I have to use it from my admin account on my computer. It is kind of annoying, but at least I found a fix that actually worked for me. There doesn't seem to be much in the way of support or customer service for free products like ADE, which is really unfortunate. There is also an Overdrive download that allows you to read in your browser, it works for ebooks from our public library.
Some Windows updates have come through recently, but other than that no changes to my system. I am thinking the Windows updates have something to do with my current issue
Thanks for the reply. I have admin rights on my computer, so that isn't an issue. However, I decided to deauthorize and reauthorize my ADE. When I tried, I got an error saying "Network error. Check your internet connection and try again." I did the Windows networking troubleshooter and tried to go to http://adobeid-na1.services.adobe.com/
The response I got was "Your computer appears to be correctly configured, but the device or resource (adobeid-na1.services.adobe.com/) is not responding."
I turned off Windows firewall -- (adobe.com is whitelisted) and it made no difference.
I agree that Adobe seems to offer no support--I've even seen a couple of sites that say they have officially stopped supporting it. IMHO, for a product that has no competitors, that is unacceptable. If I can't make ADE work, I can't read several time-limited books that publishers are counting on me to review.
Glad that worked for you. Hope somebody else has other ideas.
Good luck with your problem. It is really too bad there isn't any kind of competition out there.
