I had a new pc and i copied lfs to a memorystick from the old one. it works fine in single player but when i try to unlock the s2 again or go to multiplayer it says that it cant connect to main server (or something like that) What to do??
And my internet works fine. Thats not the problem.

Firewall issues perhaps?

Make sure you're using a recent version of LFS. The current version is 0.5X10

maybe. what should i do? i have just the windows vista firewall. I also hav norton internet security.

Ok. it was that nortons fault. i turned its firewall off and now it works.
Case closed

If I can put on my grouches hat for a moment, it would be nice if you, or anyone come to that, would put a title to the thread giving some sort of clue as to the help you need. HELP MEE!!!! doesn't hack it.
/puts hat back on peg.
