Fire texture and Dark Oak texture not showing up

Whenever I catch on fire, the texture for it doesn't show. Only Purple and black blocks. Also, dark oak block texture won't show up and they crash my game when placed. The picture on the left is me on fire. The one on the right is hard to see but when holding the dark oak blocks, the description that pops up is "Oak Wood".
