When I open up Hammer it is normal, but when I click File > New. It pops up this message "No textures are available for use with that game. You must set them up in the Textures tab of the Options dialog box before you can edit maps for this game." Next I clicked "Ok" then it brings up the "Configure Hammer". I looked under everything for hours and came up with nothing. Anyone know how to get the textures to become available?
