My Minecraft is broken

Hi Minecraft my Minecraft has been broken and that happend when I went to add the Fantersy texture pack and the top said Minecraft pe and it don't say that now and when I hoped onto a wold the Loding screen was the old minecraft, and when I went to get something in my inventory there was nothing there. So I would really like if you fixed that and I am sure it is happening to a lot of other people in the wold that plays Minecraft.

(I love Minecraft so much)
