[NEEDS INFO] Cant find Caulk in Netradiant

Hi

I tried to make a map today
My problem is that i cant find caulk in the texturebrowser
it isnt in common
I get some errors if i open common in the browser:

Unable to find default tag file D:/netradiant-1.5.0-svn402-win32/NetRadiant/nexuiz.game/shadertags.xml. No tag support.

Texture load failed: "textures/common/invisible"

Texture load failed: "textures/common/mirror1"

I searched over google and somewhere it meant that i would have to create a tagfile by clicking plugins/shaderplug

i did this
now the error:

Unable to find default tag file D:/netradiant-1.5.0-svn402-win32/NetRadiant/nexuiz.game/shadertags.xml. No tag support.
dissappeared but i still cant find the caulk texture ;(

im not sure if the caulk texture is somewhere else or what i have to do :o

can someone help me ?
sry if i posted in a false part of the forum o.o or if this is a mega noob question

It's so embarrassing when you can't find your caulk
