I am trying to open Sound Forge on my computer and it says I have to register. When I try to register from the software message box, it repeatedly says (over several days) "error occurred while communicating with server". I last registered 11/14/2017 and activated it then. When I try to activate it now from Magix website, it doesn't accept the Machine ID I used in 2017. It doesn't accept my current device ID or product ID. I would like to continue to use this product. Please help!
