LFS wont let me online any ideas

Have you got a firewall blocking it? What error do u get?
When you open LFS Press "Shift + F4" and that will put it in a window.
Then, try go online and see if any other programs pop-up and messages.
My guess is that it's windows defender, so you'll just need to "allow" it connect to the internet.

nothing popped up, and the game is on now
