There are no Magix staff present here so no-one can email you any activation code, sorry!
However, you say you purchased PS 2026 on disk. From where did you purchase it? Magix software supplied on disk will include either a Serial Key (beginning P3-) or a voucher code (so NOT beginning with P3-!)
I purchased this program quite a few years ago but only use it a few times every year or two. I am being asked for an activation code & I no longer have the box. what can I do?
Visit www.magix.com and click the persona icon on the top right to get to the Service Center. Login with the email address you used using the product years ago and you'll find it then in the "My products" section.
