I need help with opening Hammer!

[Krenshaw Addison]

When every I create a new map, it says "Missing material editor/wireframe..." how do i fix this?

You're probably trying to run Hammer through Source SDK. Don't do that, open Hammer from your Team Fortress 2/bin/ folder instead, and preferably make a shortcut to it for easier access later.
