Hi, I have problem with LFS - after some time without playing, I want to start the game, the screen goes black and then back to my desktop. 
I didn't find a solution to this yet. 
Reinstall didn't help.
I was wondering if maybe someone had such an issue and solved it? 
I have tried some things from the internet - I have the hkey_local_machine registry product id thing done. I also did try to fill cfg.txt with: 
"Start Windowed 1
Antialiasing 0"
but it also didn't help 🙁
