Q: iMessage don't send and receiver are "not registered"
On my MacBook Pro i have problems with the iMessage.
I did active with my Apple-ID Account and be connected without problems. But when i like to send a Message, i get the Error that the Receiver is no registered by iMessage.
Also i don't receive Messages on this MacBook.
It works on my iPhone5, iPhone4, iPad3, iMac in the office and iMac at home. But not on this MacBook.
It did work before till begin of January 2015.
In the Console i did find:
[Warning] Needs deletion: NO (Registration info (0x7ff63a7a8dc0): [Registered: NO] [Type: AppleID] [Device Name: (null)] [Service Type: iMessage] [Env: (null)] [Main ID: ....
What i can do ???
Did try to disconnect, also in my iPhone, reboot and so on, but all in vain
MacBook Pro, OS X Yosemite (10.10.1)

Today i did boot my MacBook in the morning and iMessage did work. I don't know why. Yesterday it was still unable to use.
I think the reinstall of Yosemite and connect into a other Network (at home now) did solve it.
