Note that when Universal Audio Driver is used, you need to start Freecorder 4 before an application you want to record from (unless you record sound from the same browser in which the toolbar is installed). Also when the driver is used, you can't record from your microphone and sounds from your computer at the same time. Try to enable "Stereo Mix" / "Wave-out mix", hopefully this will help.

If you have other problems with Freecorder 4, make sure to install Firefox instead, because it is much better than Internet Explorer and works much better with Freecorder.

You can get much more help on Freecorder 4 in the following forum:
