I purchased Movie Studio 17 Platinum from Best Buy. Sound Forge is in the products I can download, but it is not listed in the serial number list sent to me by Magix.
Welcome to the Magix Sound Forge user-to-user forum. This is not staffed by Magix employees, so no one here has access to product serial numbers, ect.
First check your junk or spam email folders. Otherwise you will need to contact Magix Customer Service which handles activation issues and such..... or try emailing sales@magix.net
