Howdy! I finally got my Block Erupter and I want to get it working tip top shape. I keep having issues after issues. Maybe someone can help?

I am using CGMiner 3.1.1 because all the other versions of CGMiner keep spitting out error messages using the same CMD line, and I don't see what is wrong, since the help output in --help shows no capitalization error, and it looks like it is all there. If anyone knows how to get the newer versions working, I will love you forever!

For CGMiner, here is my CMD line in my batch file:
cgminer-nogpu.exe -o stratum.bitcoin.cz:3333 -u kodan50.worker1 -p ThisIsNotMyPassword --icarus-options 115200:1:1 --icarus-timing 3.0=100 -S //./COM6

I read that HW error under 1% is normal, but since I have an older version that just had HW numbers, how do I know what the percentage is of my errors? And, what can I do to keep the errors down?
