You didn't fully reinstall it. Firstly, uninstall. Then delete your whole Wolfenstein folder. Then reset your pc. Then install it again. Then reset your pc again. Then you are ready to go ;)
The installation is faulty or theres a .pk3 pack from a pub for "funny" things like xmashats and so.. they are usually named like 02383185.pk3 or PUBNAME.pk3
I don't think its etmain, Because when a mod is loaded on the main screen, You get the downloaded crap showing. Etmain doesn't do that, Might be jaymod, Etpub, or whatever mod he uses.
same prob. here since jan'07 :<
when u r lookiin ur demos it sux also? :<
I see these textures as the ground on supply when I'm watching a replay ^^
btw re-install your ET for this you got a pr0 mod on gg!
