I realize that this is about three years since you have updated this page, but I have seem to run into a bit of an issue. You see, I got the name of this mod confused with one I used fro SR3. I was surprised to find that it actually works and though I had the right one. HOWEVER, It didn't take more than 3 seconds to realize what happened. I proceeded to promptly walk off of the roof to find that I now have wedged my head in the ground. It was at this moment that I realized that I screwed up. I have tried to uninstall then re-install the game, but to no avail did it change anything. If you or anyone who knows how to fix this, please let me know. For now, I guess i'm a supersonic ostrich.
Just remove weapon_costumes.xtbl, customization_items.xtbl and camera_free.xtbl from your SRIV root folder where you installed the game and remove plym.xtbl and plyf.xtbl from the "tables" folder inside your root folder.
