lfs.exe was downloaded from this page and it installed the demo version of LFS. After playing 15/30min in order to check that G27 was well set up, I came back to lfs.net and bought S3 License (bought it on Feb 01st).
After that I couldn't unlock it any more.
Guys, as a reply to above quotes, yes. That channel you are looking at YT (MrJoelAlonso) was made 7/8 years ago, and those vids you were looking at were made using a cracked version of LFS. That YT account is no longer being updated by me or anyone else.
Nowadays running a complete different PC (in fact on Feb 01st was the FIRST time LFS was installed in the PC I currrently use), my goal is to support devs to develope new contents and to support their efforts in keeping game up to date as I'm doing with Assetto Corsa, pCars, Automobilista and 10 other differents sims I bought via Steam.
Ped, many thanks once again, will try that and lets see what happens.
Once again, many thanks guys for taking the time for reply in the thread and for taking this up.
I can't get LFS 0.6r unlocked, firewall was set to allow LFS. As said in title, I bought S3 License few days ago, but it's impossible to get it unlocked.
