I had the same problem and tried to uninstall, install again etc.
At last I searched the registry (Windows XP) for AdobeID and changed the value with my new idname.
Perhaps not the official way, but it works...
Hi, Thank you for the info. I opened a case through the Adobe web portal which is apparantly in the process of being seen to. However if all else fails then your idea would be worth a try.
Seems like a plan - may solve my issue I have raised under another post "Adobe error (-432).
Tried your suggestion, located the AdobeID in the registry and change it to the correct Adobe ID, it is now showing the correct AdobeID but I still cannot open the e-book. However when I login as administrator and re-install ADE and provide correct AdobeID, I was able to read the e-book. So at the moment whenever I need to read the e-book I have to log off and log back in as administrator. I still need to resove the issue.
