Serial Number is Invalid
Posted: Mon May 05, 2025 6:30 pm
Hello,
I bought version 14 back then, which I've now reinstalled. (Okay, it's a very old version, but you should always be able to register it, right?) I just can't register/activate it. I get the following error message:
The specified serial number is invalid, please....
Do serial numbers only have a short lifespan? (I wanted to register it with the installed version 14)
(Version 20, which I installed for testing, doesn't work either)
On the homepage, however, the old serial number is accepted for an upgrade.
Or am I doing something wrong with the login/registration? (The activation server is working/shows as active)
Thanks for your help
Helmut
