Help with bpe files

[KeiroStarr]

So I looked around for this info and I couldn't find it anywhere, so I figured I'd ask. I've been trying to edit some textures from WWE '13 on the Wii. I have to use X-Packer because brienj's PAC Archiver is currently down and there doesn't seem to be any signs of him re-uploadng it in the near future. Now I open the PAC files and get to the bpe files, but if I extract or uncompress them, they always come out as the bpe file itself. I want to edit these textures, but I don't know how to open bpe files, and I can't open then with X-Packer because it says that it's an invalid pac file. is there another way I can somehow edit these files so I can extract, edit and insert new textures?
