Does anyone know how I can purchase a serial number to upgrade the Noise Reduction 2.0 plugin from the demo to the full version? It doesn't appear to be available on the Magix site or o what's left Sony Creative. The Phone number provided to "upgrade by phone" is out of service and the "Sony" link to purchase just sends me to Magix site. Frustrating. The Plug-in is useless in demo mode. I'd be happy to buy it if I could figure out how.
