I'm at Vega hideout but nothing ain't happening.

After or before Empty?

Before empty

You mean, You're in Bermuda Labirinth? Or searching for it?

I'm in it and at the end of the labirinth where the Mu symbol is at I went there and nothing happen.

I just got there but nothing is happening.

Well, if you haven't beaten the game you don't get anything. Before you can get anything you get an email from a mysterious person who goes on about scripts(Easy to geuss who he is) and he says go to the hide out in the bermuda labyrinth, then you go there and see an orb with rings around it, you go up to it an hit A then you leave(Well there are a few other items there, just click around).
