Hi, I have a problem with LFS because I'm waiting already another week to be able to play online but I can not unlock all the time I UNLOCK ALL IN THIS WEEK WERE USED help !!!!!!!!!!!!!!!!!!

You have to pay for a licence to get unlocks. https://www.lfs.net/shop/

You could email the dev's for some more unlocks I guess, or consider making a new account to be able to play online with. As it's only demo anyways.
