App store won't update - "we've run into a problem"
I have five updates but when after clicking update, a pop-up says: "Apple Media Services Terms and Conditions have changed. To proceed, you must read and accept the new Terms & Conditions." I click 'okay' and then and 'agree' but then a pop-up comes up and says "We've run into a problem". And no update occurs. What is going on and how can I fix this?
