Hi, I've been having problems setting up Home Sharing on iTunes. It keeps telling me 'Home Sharing Could Not Be Activated Because The Account OR Password Was Incorrect'. I've reset my Apple ID password to see if that helps but no joy. I'm definitely putting in the right details. It's worked in the past, I was just setting it up again. Now I can't stream to my Apple TV or swap music between machines. I've tried restarting the router, restarting all the computers etc... but still the same. Any suggestions?
