<li> after i add vertices for a face, and then i add a face to it, it wants to go cross-ways like an X, and not a regular square. so in game that face messes up cause it isnt right..
If you put the verticies in the right spot and you define the face in a clockwise direction then it should work fine. If that's not the problem, then maybe you can say a little more about what you mean by cross-ways.
<li> when i also goto look at it in game, the ends of the faces are black marks, and dunno what i did wrong.
Did you map the faces to the textures after you defined the face?
<li> is there any instructions for this?
This is the help page for binedit 0.9. Binedit 2 doesn't work exactly the same way but the instructions are step by step and very simple. Reading it would help get you familiar with 3D concepts and how they work, and would be a stepping stone to binedit 2. However, before you get carried away here, see the next links.

This is a basic tutorial for binedit 2. I think it's the proper place for a beginner. In your case, I think you might want to put your project on hold, do this, then go back to your project with what you've learned here. It should be enough to get you rolling. If you still need more or are having problems, maybe then go back and look at the 0.9 pages. With what you've learned from the BEI tutorial, the 0.9 pages would make more sense and be easier to follow.

This is a general help page. It's not a tutorial but will explain how everything works. If you forget something from the above links, or wonder what some part of the program does, then go here and freshen up on all the info. It's also a quick and handy reference page. Note. This does not include the truck editor or other features in the beta release. It does, however, cover everything else.

The keyboard layout, of course, is on the help menu in the binedit program.
