Hello ! I've got a big problem : I just bought LFS S2, the best racing game I've ever played, but then I had a huge frustration : I can't unlock it. When I click on 'unlock', I can't connect with master server. I also tried to play online and I can't cnnect too. So I think it's because I have a router but I don't know how to configure it, I don't know much about those things. Please help me !! The router is a Speedtouch 706 WL.

What version of LFS do you have? If its not a recent one, it will not work as previously the LFS master server was hardcoded. In newer versions it is not.

If you do have X10, then have you seen this thread? Answering some of the questions will help us help you.

if you entered everything correctly (turno off your firewall for about...2 mins...and then do it, if it goes successfully it should say Welcome to S2, i remember when it said that to ME for the first time...Ahhh

Ok problem resolved, "welcome to S2", great. thanks
