on both lfslapper and the cruise example it says pw doesnt mathc but it matched.
what im doing wrong??

It's the admin password that InSim uses. You'd only get that if it weren't the same.

If you're trying to run it on single player, go into Multiplayer > Start New Game, and then clear any admin password, or ensure it is the same as what you've got configured in lapper, etc.

i know that it is the admin pw, thats why i wonder why it doesnt work.
the same on .cfg and ingame (Alfons)

update: got it going but having another prob: my laptop wont connect anymore since i forwarded the ports (i have a dlink di 524) inet on the desktop pcs still works i need FAST help, my dad is going to kill me if im not solving this

I had this problem before when I wanted to host sometimes from laptop, and sometimes from PC. What you need to do is change the game port in LFS on the laptop to some random number, I use 27010. Then you can forward that port to the laptop's IP. Or, everytime you switch between laptop and PC, you can change the IP to be forwarded to...
