iTune Error Message Pop Up - iTunes Store Request
I have three Mac Book Pros (Retina, 15-inch, Mid 2014) running Yosemite (v10.10.5) that I use and each of them now have the same pop up message every time I use iTunes (v 12.3.0.44) when I'm not connected to WiFi. I will be offline playing music off a playlist of songs thats located on my computer and a pop up will come up at random times (lucky it doesn't stop the music) but I'm forced to keep clicking "OK" to the message. The message states " We could not complete your iTunes Store request. The network connection could not be established. There was an error in the iTunes Store. Please try again later." I also have been getting an error message about the identify or verification certificate on play.itunes.apple.com???? Any help please...
