This a pack with all (I think) of the MUA textures in PS2 igb format. Just unzip and paste them in your textures folder. I wouldn't recommend replacing as it is not necessary, so just keep hitting no and it will just place in the MUA textures that don't appear in XML2. This should clear up any of the blotches instead of powers problems for all mods.
