the serial number for samplitude music studio didn't come with the cd or the box. I've looked everywhere for it and I can't find it. I really want answers for this because I paid 60 dollars for it. I also bought it off amazon prime so that could be a reason.
Since you bought the product from Amazon you will need to pursue this problem with them.
As a user to user forum, not a contact for Magix Support, no-one here is likely to be able to help you; even Magix Support will not be able to do so either because they will have no record of your purchase.
