iMessage on Mac OSX not working

Suddenly my iMessage on Mac OSX stop working.
iMessage asks me to fill the password, but i got an error even if i fill the real password.

Here is the error:

The registering device does not have appropriate credentials

So i am browsing to get an answer and i got a website that fix my problem.

What you have to do is, open a terminal, and add this:
killall imagent


and some people suggest to reset PRAM.
