Hi, I'm new to Bitcoin Mining and this Forum...

I'm using Bitminter and 5 Block Erupters at the moment and they worked fine for the first 2 days, but now they're not profiting and my stats (BTC Miner for iOS) are not updating, thus my mining has come to a halt. My BTC is not climbing at all on the App and Bitminter.com . The hash rate continues at 1.68Ghash/sec and still no profit for days. I have made just over $2 AUD. Is there any reason why this is happening? I really want my rig to keep mining efficiently. Any help is greatly appreciated.
