My Yamaha AV RX-V675 Reciever AirPlay icon will not click on.

I have just purchased a new Yamaha AV Receiver RX-V675 which is AirPlay capable. I have everything installed and configured as per directions in the Yamaha manual and according to Window& and iTunes directions. iTunes AirPlay icon shows the receiver (with a speaker icon). However when I click to initiate the Yamaha it will not execute nor will a check mark show up. Everything seems set up correctly as far as I know. I am looking for help and a solution. I have updated my firmware on the Yamaha and set up with the following equipment configuration:

• Dell Studio XPS
• Win7
• Yamaha is on a hard wired network connection
• iTunes 10.2.2.14
• W7 set up for HomeGroup network and sharing
• Router - Netgear WGR614v9

Problem is that the Yamaha AirPlay icon in iTunes will not click on.
