Do you use the original Minecraft Launcher (Minecraft.exe from minecraft.net)? It looks like you don't use one, because of:

 

Exception in thread "Thread-10" java.lang.RuntimeException: cpw.mods.fml.relauncher.ReflectionHelper$UnableToFindClassException: java.lang.ClassNotFoundException: net.minecraft.Launcher

 

 

It cannot find the net.minecraft.Launcher class, which should exist if you use the original launcher.
