Hi... i made what u said.. but then i can't turn my server on ... it says file /maps.txt corrupted somthing... am i making somethin wrong or ... i dunno what 2 do?

I'm pretty sure your map is not in the lava directory. I have changed the directions a bit on that post.
How to fix?

You need copy your map over into the folder "\lava\maps"...or next time before you start you need to do: /savelavamap [mapname]
