OreRockon,
Here is what you need to do, that should fix your issue. Nvidia has finally fixed their drivers, so there is a beta driver that will fix this issue.
This was just fixed with their driver in October 2011, but the latest driver was released today 12/21/2011.
Here is the Link to the Windows 7/Vista 32 bit version

You are also running Karaoke Home Producer 5.0.08 so you need to upgrade this to version 5.01 from here
