I went to register on my new desktop computer but it is telling me that someone already has this on their computer. I just need to be able to use it on my new desktop computer, and hopfully still be able to use it on my old laptop. PLease help?
Like most, if not all, Magix products Music Maker can be activated on a maximum of two devices simultaneously so, unless you deactivated the software on your old desktop computer, the registration server will not allow you to register and activate it on your new desktop.
The easiest method of resolving this is to go to your Magix Account, log in, go to My Products and find the listing for Music Maker. You will find two devices listed as activated, your laptop and your old desktop; select the latter and Deactivate it. Then go back to your new desktop and you should be able to activate its installation without problem.
