iMessage - Facetime not "connecting" mountain Lion

Hi,

here is my problem.

I just updated to 10.8.2 from Lion, and i got two issues in iMessage and Facetime. When I try to connect to my icloud account, the app keeps for 3 mins triying to log me in, but it shows a message saying "could not connect to server, please check your internet connection".

How I know the internet is not the problem? because I`m using the same mac to write this question.

I tought the problem was my iMessage app, beacause I was using the beta version before the update, so I deleted it and reinstalled Mountain Lion, still no success

Some advices and solutions triyed:

1. Switch beteween ethernet/cable and WiFi. no success
2. Reinstall M. Lion. No success
3. Look for the com.apple.facetime/imessage file on the library. There was no such file in that folder.
4. Check if 2 iCloud accounts were on the app. There was one 1 account
5. To check the internet - wifi - account. I used my iPad and iPod Touch to send messages and I can send them from there.
6. Try to log in with another account or fake account. No success, same response
7. Use another account to log in with iMessage, like gtalk, it did

I can use my iCloud account to everything else, but this.

So... that`s it... if there is another solution, please tell me
