Can't record from internet



I’m trying to use Nero Wave Editor to record sound/audio from the internet. When I select record and select OK in the Sample Format Settings window, a message pops up that says Unable to open recording device. I had Nero on my last computer(XP) and I had to go into the volume mixer and unmute an output, but my current Windows & only shows microphone and line in. How can I get Nero to recognize audio from the internet?
