Cannot "Register this computer" with .Mac Sync
I am unable to sync anything via my .mac account. I have tried umpteen times to open System Preferences > .Mac > Advanced > "Register this computer" and it never registers my computer! Unregistered, it won't sync.
I have tried this on both my iMac and iBook, and both have the same exact problem. I have tried logging out and in again. I have tried restarting. I have tried going to System Preferences > Sharing > "Computer name" and changing the name of the computer to something other that what I used to have it registered under. I have tried repairing permissions. I have tried typing permutations of "mac", "sync", and "register" in every search engine I can think of and every Mac user Web site, and nothing! I cannot find another person that is experiencing this problem. I can't believe I'm alone in this, though!
Oh, and of course I searched the Apple Support, Discussions, etc. and the system is down.
Anyone know what the problem and solution is?
