Home Sharing and Apple iTunes.

Here is my issue, I have the latest version of iTunes running on my PC with home sharing turned on. I have Apple TV, and can go to my PC and view and play all the music I have on iTunes, no problems. Now on my iPad when I access the music app I used to be able to click on home sharing, to see and listen to my music on iTunes on my PC. Now it just displays purchased items ? When I try to access home sharing a red circle comes up and looks like it's loading music from iTunes but stops about half way and shuts down ? This was working fine ? I thought it may be iTunes upgrade to the latest version ? I know it's not my wireless router because Appple tv is working fine. I have turned off home sharing on iTunes on my PC and turned it on again as well as my iPad.

I am not sure what I did, I turned on my AppleTV to access my music on iTunes. It worked fine, I turned it off and now home sharing music is working fine on my iPad music app ? Strange. Thanks no need to reply.
