I sent my settings over to the support people at jonesgear, where I bought the miner. They are using my worker on one of their miners. that same exact information will not work for me.

So yes, my worker is in the right format, and yes, I created the username on btcguild.com

There is only one pool in there (listed 3 times), but on your suggestion I made another one on another site to see what would happen.
