cant get the Mincraft to open to the main pag

What I expected to happen was for it to let me get on and play Minecraft.

What actually happened was when I pressed play it opened it up it said Mojang and then it closed and said this:

:48 ERROR]: Game ended with bad state (exit code 1)
[15:57:48 INFO]: Deleting C:\Users\Brandon\AppData\Roaming\.minecraft\versions\1.7.7\1.7.7-natives-546963589576

This only happened on 1.7.4 and above.
