Well you need to have extracted the packs first, presuming you have done this...

1. Click on the button that chooses the directory to find textures

2. Then pick the folder

Rome - Total War\Data\packs\DATA\MODELS_UNIT\TEXTURES

3. Then check the box that says "force texture path"

4. Now when you import the models they have textures!
