Please check your system date is correct.
I have checked the date and time. I have also changed the date and time to eastern standard time and central time that did not work. I have also disabled my firewall and I have allowed the program access through my firewall and that did not work. I have tested my internet connection and i have clicked on Adobes tests and they work. I have also uninstalled and reinstalled the program again and no luck there either. Do you have any other ideas? I spoke with Amit at customer service and he is going to escalate the issue for me.

Now LAunch ADE and try to authorize.
Hi Shreya, The instructions above kind of worked. i got the program to authorize now when i download the book into the program it says error check authorization. I am down loading the book in Firefox not Internet Explorer. I just tried internet explorer and I got the same error message as Firefox. Thank youJulie
The error that i am getting is ERROR Check Activation and the program will not let me download the book into it? The instrucutions you sent me did let me activate the program. I am downloading the book using Firefox. I tried Internet Explorer and i got the same error message.

Follow below steps:
Choose Start > Run.
In the Open text box, type regedit and then press Enter. The Registry Editor opens.
In the left pane of the Registry Editor, locate the following registry key:
Right-click the Adept key and choose Delete.
In the Confirm Key Delete dialog, click OK.
Your authorization will be deleted.
ADE will be deauthorized now.
Now Authorize ADE again. [Launch ADE; Help-> authorize computer.]
This will solve your problem !!
I am just trying your instructions now and i get into the registry and there is nothing that says HKEY_CURRENT_USER\Software\Adobe\Adept. My computer just says HKEY_CURRENT_USER and there is nothing in there that says Adobe software. I can deauthorize ADE from the program itself should i do that and reauthorize it again?
I figured it out and it is working i was able to download the book. Thank you so much for all of your help.
I'm having the same problem, but I can't get it to work. How did you fix this issue?
What worked for me were Shreya instructions on resetting internet explorer which was step 3 in the process. I can send the instructions to your email if you cannot see them on Adobe forum.

Hi, I have the sameADE computer authorization problem but have Microsoft Edge browser rather than IE on my windows 10 laptop.
I have deleted the registration key for Adobe adept, and cleared all personal data from Edge, but still get the same error when I try to authorize my computer, ie "Activation Server error..... Digital Editions encountered an error on the activation server". I have spent several hours on this and would really appreciate any advice you can give. Thanks!
