LFS recieves no reply from main server

[Kisiel]

Hi all,
I'm back to the game and i already have some problems,
when i launched game it said i have to unlock game again, so i typed my username and password and pressed "unlock" button.
After i did this,i waited for connection, but never had one.
Game repetitively says "no reply from main server"
Is there anything i can do about that?
I have checked the task manager and it says LFS uses no network :/
Thanks for your help!
