Errors working with OS X 10.9.2 and iTunes 11.1.5 (5)
Urg! Getting so frustrated! I had our computer's hard drive and RAM completely upgraded and we're now running OS X. Everything is working great except when we try to use iTunes. If we try to update Apps we get an 'unknown error (-50) message and when we try to authorize our computer (because, apparently, iTunes doesn't recognize it anymore) - then we get an 'unknown error (5002) message. If we plug in any of our devices, iTunes said it will clear them of their content unless we authorize our computer.
Grrrrrr.
