ok in ZE when i go to water mode and i put in mus1_main_2 wich is lava texture

what are the other codes there?

Go to Mustafars .req and get the code from there.

Putting the texture into that little box in water edit mode doesn't work.
You have to go to your ***.fx, which I assume you made if you followed AceMastermind's water tutorial correctly.
Under the PC parameters for water, delete your current stuff and enter this:

PC()
{
Tile(1.0,1.0);
Velocity(0.01,0.02);
MainTexture("mus1_main_2.tga");
LODDecimation(1);

RefractionColor(160, 100, 0, 255);
ReflectionColor(204,51,51,255);
UnderwaterColor(204, 85, 0, 200);
FresnelMinMax(0.2,0.7)

NormalMapTextures("water_normalmap_",16,8.0);
//BumpMapTextures("water_bumpmap_",16,8.0);
//SpecularMaskTextures("water_specularmask_",25, 2.0);
//SpecularMaskTile(4.0,4.0);
//SpecularMaskScrollSpeed(0.0,0.0);
}

It should work that way if you set up your water right.
Oh, and put the mus1_main2.tga into your world1 and effects folders.
If you don't have an effects folder, make one.

And Commander_Cody, I don't believe you have to do anything with the req files........ at least I didn't and it worked fine.
