Hm, i never really had this problem before.

ok so im just going to take some guess.

1. It downloaded wrong.

2. Try downloading it as a Zip file (Got my last build like that, cause the Launcher is broke)

Oh wait, you said you updated by the launcher. Its broken at the moment, just download the latest Zip file, if that dont work, im not really sure what the problem is.
