I can't seem to login in to iMessage - when I do, I receive the following error:
The funny thing is, this happens on both desktops I own, so I can't believe it's a computer-specific problem.
iMessage works with the same Apple ID account on my iPhone and iPad.
On one of the machines, I've tried:
* fixing the etc/hosts file
* making sure date/time is correct and set automatically.
* deleting all Messages plist files
* deleting Keychain access entries for Messages
* and probably more that I can't remember right now.
What is going on! Any help? FaceTime, iTunes, and the Mac App Store all log in just fine.
Mac Pro, OS X Mountain Lion (10.8.2)
