The activation server is back up so the error 256 would seem to be related to something else. As Michael mentioned I would recommend you post your inquiry to the Adobe Digital Editions forum.
when this happened to me, they said it was because their server was down and that all i needed to do was wait
until they fixed it. It took about 1 day to get it fixed. Just keep trying to get authorized about every hour or so until
they fix the server.
We had another outage yesterday during the morning PDT. You can always review the Digital Editions support portal at http://helpx.adobe.com/digital-editions.html as well as contact support at http://www.adobe.com/support/digitaleditions/supportinfo/. To determine if there is currently an outage.
No the activation server is available today. If you are still experiencing difficulties I would recommend either contacting support from the link above or post your specific difficulties in the Adobe Digital Editions forum - http://forums.adobe.com/community/adobe_digital_editions.
I am still getting the error 256. I did a live chat but they don't do the support. I had to create a support case & submit. I am on Adobe.com on both my iPad & my computer so I am not having problems there. Are you getting the error on your iPad in Overdrive while trying to authorize Adobe so you can download books?
Thank you I'll try the other forum since I cannot access the help link. How often does adobe employers look at those questions? Someone posted 2 days ago with the same issue and it has not been answered.
Yes I am, overdrive worked very well until a few days ago. I cannot even open adobe.com from my iPad or another computer it says something about the server is not responding. I'm not sure if that is a problem on my end or adobe.
Have you tried unplugging your router for 5 seconds or more to disable your Internet then plug back in and try to see if you can access the server. Sometimes that helps me when I have Internet issues.
If you aren't able to access Adobe.com on two different devices utilizing the same ISP. I would recommend contacting your ISP. Is your router also your cable modem? Even then failures as specific as not being able to access a particular site will either be within your router settings or something on your Internet Service Providers end.
Internet provider says everything is working properly. At one point today I was able to access adobe cache page from yesterday afternoon on a desktop in our house. Any other suggestions?
All your time and effort is greatly appreciated.
