Can't sign in on iMessage and FaceTime after upgrading to ML
After doing a clean install of ML, I can't login anymore to iMessage and FaceTime. I'm correctly login to iTunes, AppStore and on my iPhone iMessage works good.
The error is "Il server ha rilevato un errore durante l'elaborazione della registrazione. Riprova pi tardi"
or in english
"The server encountered an error processing registration. Please try again later."
The problem is in ML because with Snow Leopard I hadn't a single problems. I'm on iMac 21.5'' late 2009.
Thanks
iMac, OS X Mountain Lion
