Hey all, I have that same problem, I can´t open LFS.exe because there comes warning "Not suitable screen modes". I have uninstalled my LFS, DirectX, graphic card drivers. Then I installed new drivers for my graphic card (ati radeon 9600XT), and new DirectX (9.0c), And LFS patch X. Nothing changed, the game doesn´t work.. I cant understand anymore what can be wrong, because I have installed all again.
