I haven't been able to sycn my itouch in weeks. Somehow Bonjour got disabled - i get the error message under the sharing tab that i need to re-enable it. I have windows 7 home premium and have uninstalled and reinstalled itunes many times trying to fix this. I deleted all my anti-viruses, made sure Bonjour is "running" under task manager services - restarted my router - unchecked the internet protocol version TCP/IPv6 - no go I just don't know what else to try.
