Pathfinder Compendium Bestiary drag problem "Building NPC" again

Hi, I saw in one year ago post. That the people have the same problem as I am having with the Pathfinder Bestiary Compendium drag shets. The shet doesn't build, and the proces stop with this message. I've tried everything, and it's not possible to finish the process I don't know why. Can you take a look and try to fix it. Thank you.
