Hi,

Please reset the hosts file:

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 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 the file.
