I wait I wait, nothing happens.
Could someone upload a backup of a working machine ?
I think it will solve that sh***...
Is it connected to internet? Try "Network" -> "Diagnostics" -> "Ping".
If its connected, double check the pool info. Don't leave the password blank even if the pool doesnt require password.
