I'm on a laptop and was about to run lfs here at my current location and now it's asking me to go through registration again? I move around and I run the game ever so often and am wondering if it's going to be like this on going where I have to register for every single location I may launch the game from?

If so this sucks.

It's one unlock per machine you install it on - when you start the game again after having unlocked it previously, it should still be unlocked.

Have you installed it inside window's "program files" directory? that can cause this issue, it's best to give LFS its own directory like "C:/LFS".

Hi, no there is nothing like that.

There have been some security updates recently, but nothing has become inconvenient.

If you tell us the exact message you saw, we'll be able to help.

EDIT: It's probably just the unlock code, that takes around 1 minute to get and use, only has to be done once, and is described here:
