I am tearing my hair out trying to figure this out. For whatever reason, the Remote app has completely stopped working. I am using OS X. I have deleted and reinstalled the Remote App. I have deleted and reinstalled Itunes. When I go to "Add Library" on the remote app, it works just fine and accepts the code. But then it just times out every time when "connecting to library." Firewall is off. I have done the "forget all remotes" thing. I have reset my airport extreme and disconnected every single connection just to troubleshoot. There is absolutely nothing I can do to get the remote app to connect to iTunes. This is very frustrating as I have used the app for more than 2 years. I swear this happened right after the 4.0.1 update. The program works fine in Windows, but not in OS X. Any thoughts or suggestions on how to get this working again? This is driving me crazy! Thanks in advance.
