ITunes radio 10.5.3 (3) stopped working
I've been using ITunes radio flawlessly for years, when suddenly this a.m. I got the error message: An error occurred while contacting the radio tuning service. Check your Internet connection, or try again later.
The rest of ITunes like the store and such seem to be working fine as is my internet connection. Nothing on my system has changed. ITunes was last updated in January 2012.
I'm on Mac book with OS X 10.6.8.
Any ideas or suggestions?
