I had installed this software on 2 laptops and no more. Now I need to use the software and it's not working - even after reinstallation. I have disabled the second laptop on my online account and it's still not working.
Try deactivating one of the two Sound Forge activations directly in SF (Help> Deactivate the software on this PC) menu. There is a 'once-a-month' limitation doing it online through Magix' service center.
