          It may be necessary to clear out the hosts file. It sometimes gets littered with extra ip addresses following attempts from the activation sever and they should all be deleted.

           

          This is what a Hosts file looks like normally.

          Windows

          Choose Start > Run, type %systemroot% \system32\drivers\etc, and then press Enter.

          Right-click the hosts file and select Open. Select Notepad for the application to open the hosts file.

          Back up the hosts file: Choose File > Save As, save the file as hosts.backup, and then click OK.

          Search the original hosts file for entries that reference activate.adobe.com (for example, 127.0.0.1 activate.adobe.com) and delete these entries.

          Save and close to overwrite the file.

          Mac OSX

          Log in as an administrator to edit the hosts file in Mac OS.

          In a Finder window, choose Go > Go To Folder.

          Type /etc

          Select the hosts file and open it.

          Back up the hosts file: Choose File > Save As, save the file as hosts.backup, and then click OK.

          Search the original hosts file for entries that reference activate.adobe.com (for example, 127.0.0.1 activate.adobe.com) and delete these entries.

          Save and close to overwrite the file.

           

          N.B. You may have to temporarily disable you security software to modify your hosts file.
