I get the error that "the Wave Input device cannot open" Huh?

The full error is "The Wave Input device cannot open. Another program may be using it." Close the other program and try again. If you have more than one soundcard, you may try an alternative device to record from in the "Recording" tab of the Preference dialog."

If you get this, you may want to reinstall the sound-card drivers for your soundcard. You can usually find them at the soundcard's manufacturer's website.
