Hmm, I have both and had no trouble installing or using them. They came in like any of the other Koz hair items. Does PPP have anything to do with it? It seems odd, though, that your other Koz hairs work fine, just these two. Sometimes an item will be a bit buggy for one person without explanation. Wish I could help, but I can sympathize. I've had files that just don't seem to work no matter what, while others have no problems. Melanie
