Hi list, First I want to thank those who encouraged me to get my logic board replaced via Apple's recall program. It ended up being a bit of a hassle, but that was due to my local reseller, not Apple. At least the deed is done and my display is working perfectly! Second, I do have a question about something else going wrong that may be related to the replacement. I can no longer play songs I've purchased from iTunes. When I try, I first get a message that says I'm not authorized to play this song on this computer, and I need to sign in and authorize it. When I enter my username and password, I then get a message that says "This keychain is not valid." It tells me to open Keychain Access, run Keychain First Aid, and try again. Well, I've done this several times, tried restarting, changing my password, etc., and I just keep getting the same message. Any thoughts?
