I just payed or LFS2 and when i login i get

Connecttocodemaster : Error opening socket??

Any one know that i need to do?

restart lfs
re-download & install lfs
try to connect to a different server
try to connect several times

that´s just the basic things to do

maybe checking the firewall settings might also help, although windows firewall allows pragrams started by you to connect to the internet even without asking.
