I made an account and activated my key but whenever I go to log in it just redirects me to this page and when I go to proceed it says "The serial number you entered has already been used. You may have already registered. Registering again is not necessary. If you have any questions, please contact out technical support team: http://support.magix.net".
I have no idea how to sign in and use the software.
Any help would be greatly appreciated :)
