anyone know what happen? how to instal it ?
In an inital install it can take some time for your Vault to find connections. But once that 10-20 minute phase passed, you probably won't ever have this problem again.
I don't think you will need them, but here is a list of nodes from our block explorer that you can add to your cryptobullion.conf file in your CryptoBullion folder.
Also there will be shortly a new Vault version with a fix regarding Vault syncing.
