oookkkaaayyyy i finaly get it  !!

For those who have problems with pre_enabled and then expired message this is what ive done :

go to : http://ping.eu/port-chk/  put you re external addresse IP and port 7209

If its closed you ll had to open a nat rule to port 7209 on you re router to you re computer.

In my case i lefted my firewall open for port 7209 but it wasnt enough i had to make the nat rule.

Sorry for my shity english hope it can help
