Open Hammer
Go to Tools->Options
Go to the Textures tab
Click on Add WAD
Browse for your .wad file and double-click it.
Press OK.
i cant browse it... im telling you the file isnt there, i can only see it using gcfscape.
open the folder where you have your .wad file (like C:\Documents and Settings\Andyetanotherdragonballzfan\Desktop)
Find the line saying "Hide file extensions for known file types" and make sure that it is NOT checked.
