OK... sounds like you are saying all I have to do is switch how I have it connected... the IN goes in the OUT spot and the OUT goes in the IN. 

I have this one:

If the fix is that simple, you have just saved me a lot of headaches, frustration and money! Going to try it! 

Thanks so much. 

Can someone please help me figure out if there is a driver for the Casio LK-43 keyboard that would allow me to use it with my computer (Windows Vista)?  

The Casio company could not help. I just need to know if I can use this keyboard or not, we have a computer piano program for my kids to learn how to play. 

Thank you.
