You are mining with the wrong algorithm. In your command you have it mining with scrypt, not sha256.
Ohh okay, so this should fix it?
You can't, you can't mine SHA256d in an academic perspective.
You can replace your "scrypt" to "sha256" or try blank. Not sure for that particular CGminer version, you're using a pretty old one. But you'll be making a few cents per year at most, it would take you years to reach minimum payout at a pool and you'd be using tons of electricity.
I point you toward the Altcoin mining support section. You can get started with X11.
