Whenever I try to access HomeSharing, my PC reboots. I have tried all possible fixes I know and not successful (reboot, restore, update iTunes, update ATV2 (originally bought a refurb) etc, etc, etc. I went to the Apple Store and they replaced it with a factory unit and still same problems. Everything else works fine, Netflix, etc. It will recognize my Library on start-up but it will not connect. Then it will shutdown my computer and tell me to turn on HomeShare. Then after 8+ years of the same log-in password, iTunes tells me it is no longer valid and I've had to change it twice since then. Anyone else have this problem? Thanks in advance.
