Apple TV not seeing itunes on Windows 7

My apple TV has suddenly stopped seeing my computer and ITunes on only my profile on my Windows 7 PC. I have no Apple TV symbol showing. The computer is on the same network , virus disabled and Bonjour repaired , Apple ID user name and password correct, sharing on in preferences. The thing is on my wife's profile all is fine, Apple TV picks up the computer, music, pics and the Apple TV symbol shows.

Is it a sharing thing on my profile. Its driving me nuts:(.
