Error when trying to open new Direwolf20 pack

[BeastFeeder]

I Installed the new launcher last night and tried to launch a direwolf20 game. Each time i recieved this error: "Error: Could not find or load main class net.minecraft.launchwrapper.Launch"

Here is the full log: http://pastebin.com/jGT2ux1U

How can I correct it?

thanks
