specular map problems

i try to apply a texture to my model with both normal map and specular

"VertexLitGeneric"
{
"$basetexture" "bankvault/bankvault"
"$model" 1
"$surfaceprop" "metal"
"$envmap" "env_cubemap"
"$envmaptint" "[0.5 0.5 0.5]"
"$envmapcontrast" 0
"$bumpmap" "bankvault/bankvault_normal"
"$normalmapalphaenvmapmask" 1
}


did as best as i could, but i get still get the message that sth aint right:

material bankvault/bankvault has a normal map and an envmapmask. Must use $normalmapalphaenvmapmask.


the working files are here:

changing the envmapcontrast doesnt doesn´t help

could you plz have a look on my bankvault_normal.vtf and check if the alpha is set up correctly? and if not correct it
