Hi angeaw,
Thanks for sharing all that detail. That "serial number can't be used" message usually pops up when the file and the licence don't quite match (for example, wrong product level, wrong version, or the file needs a fresh licence refresh from our end). I've had a look and can see you've already got an existing support case open for this. Since the serial number and activation issue needs to be checked on the back end, it's definitely one for our support team to dig into properly and get sorted for you.
Regards,
Sai
