@rob-b3225 If I remember it correctly, you can use the software for 7 days until you need to enter the trial code. But maybe this isn't possible in the newest version? It can take some time until you'll get the number.
We can't do much about this. This is a user forum and not Magix support. We are all users like you. Maybe try to contact customer service at infoservice@magix.net.
