Halp With Optifine

The launcher updated and now everytime I try to start the game with Optifine it gives the message "LAUNCH FAILED The version you are trying to play inherits properties from an unknown version of the game" I've already launched the game like normal a few times, and it worked just fine yesterday :/

 

Open an explorer window and at the top url bar enter %appdata% like so :

Then open up the .minecraft folder as you see here :

Scroll down and delete both of these files if you see them :


If you don't see them I'll continue with this post.

 

Still giving me the same :/
