sorry but you throw your money away.
first thing, forget about btc mining with gpu. as you can see you can't earn anything with it.
second thing, 40GH asic is obsolete right now and also won't earn you anything.
even if you have free electricity with 40GH you will earn around 0.00049916 BTC or $0.19/day on this diff and btc value which is miserable earnings.
