My Texture packs and add ons don't work anymore. Two texture packs work though, the classic and city texture pack. 

The texture packs which don't work just use the standard texture pack. 

The add ons just don't get into the world. The guides don't spawn in the hot bar and crafting them by memorization doesn't work either because it won't work. 

I deleted the save files and reinstalled them. 

I cleared the store cache. I tried restarting and it didn't work.
