cannot connect to itunes radio
I used to listen to the radio each day, but now when I try to connect I get a message that says that an error occurred connecting to the internet, try again later.
I ran the troubleshooting for internet connections - passed, I can connect to the itunes store in itunes, my home sharing account is working, obviously my interet is working, I have disabled my AVG security and added another exception to the firewall for itunes, as well as turned off the windows firewall. I have the latest version of itunes, I have tried to connect on a different wireless network but it still doesn't work.
Windows 7, wireless connection not working
