This is why it's so confusing. I see that Magix attempted a withdraw to my debit card. Nothing at all about Boris. In my searches I saw the name Boris, but had no idea what it was. I guess I need to purse that. Thanks for the info.
Yes, as this post confirms, BorisFX now owns SoundForge.
However, I note you list Sound Forge v 18 and 19. These are versions produced by Magix so it seems you do need to contact them! (I admit I was not aware that it was necessary to pay yearly for SF?)
Have you tried sending an email to infoservice@magix.net to explain the problem and request their help?
