jack hammer textures not working

so ive recently set up jackhammer, but whenever i add my old .wad's that i used in worldcraft, the program just crashes.. idk why either.. But the bo2 textures from friizy works with it, it just seems every other wad/texture wont work. please help i'd like to get back into mapping

ok so i got the textures working by making into a wad2 instead of wad3, but now they're all black and white? this is really frustrating. what should the textures files be? (wad3, wad2, hlwad, etc.)

The textures should be hlwads; good on you for figuring out how to change them (:

However Jackhammer sometimes screws up, and the textures show up in grayscale. Unfortunately there is, right now, no way to move past this besides converting your wads into hlwads again.

Sorry ):
