When I try to add the warthognew & gwarthognew tags from this site into a map I get this:

Dose anyone know how to fix these togs or Know where to find working ones?

did you put the tags in the correct places?
read the readme.txt that comes with the tags, they should tell you where the tags go.

It dose'nt have a readme.txt. it just has the folders h2\vehicles\hogs\g_warthog or h2\vehicles\hogs\warthog.

The tags look like they're in the right place, else the gbxmodel and other more essential files would be missing.
