HELP with iMessage! (not a login problem)

[Azimuth1]

Hi there,

ML 10.8.4 installed and perfectly working ... till yesterday ... now iMessage is not working anymore!

I can login and logout from the service but when I try to send a message to one of my contacts I get the info "Messages cant start the chat - number xxx... is not registered with iMessage", and this weird behaviour is valid for all of my contacts.

I have Chimera v. 2.1.2 r.2248 installed with fileNVRAM 1.1.2 .

Any hints?

Not really sure what the problems is, i think I am geting the same error.
It says that the user "is not registered with iMessage", despite them being so.
Although all contacts do not work for me
