When we add the serial number we get a connection error. We arent sure what could be causing this. Any ideas on most common causes you see with this error message so we can troubleshoot and resolve? Thank you.
This happens if a very old version is installed, that is no longer able to connect to the secure verification server. Please make sure to manually install the newest update (download it from your purchases dashboard then install). After that it will be able to connect to the verification service.
