I followed all the directions. I exracted the wrapper into a folder, downloaded the .Jar file into lib, I go to autorun, and it tells me
Could not find the main class: Main. Program will exit.========================================Warning: lib\minecraft.jar not found.Did you read instructions / download it?========================================

I have done this several times and even different ways and it still won't run. Am I missing something?

I will add pictures.
