Had all my iDevices on iOS 6 Beta 4 and Mac 10.8 finally linked with my phone number and iCloud/.Mac/Gmail addresses. Messages on my Mac Pro were coming in well, all my devices received my texts. Then today I logged in and my phone number is no longer associated with Messages on my Mac. All my iDevices are linked to it, but for some reason my Mac only recognized my emails account. Reset Messages.app, checked all my accounts, doesn't make sense. Any help, I would greatly appreciate it.
