I've changed my harddrive to SSD and now need to re-activate Samplitude 11. It says I have an invalid serial number. Was running fine on my old hard drive (still is if I swap back). The website activation center also says I have a wrong serial number. So, basically I'm trying to raise a support ticket with Magix, but I can't for the life of me find where I can do that. It just takes me around in circles. Does anyone know where I do that? If so, perhaps you could post a link for me where I can raise a ticket, cos darned if I can find it...!
