Can't play music since iTunes keeps asking to authorize this computer
I bought a new macbook and have authorized iTunes - I have 4 out of 5 available. It says its authorized, but when I go to play a song the popup to authorize this computer comes up. Basically it ignores the fact I have authorized this laptop.
I tried shutting down and restarting. Restarting iTunes. I tried deleting the /Users/Shared/SC Info directory as was mentioned in another thread. Did not help.
MacBook Pro, OS X Yosemite (10.10.5), iTunes 12.3.0.44
