BFF miner is not seeing any of your hardware so you are not mining. The new block detected means the network has resolved a block and we are all working on the next. And by we I mean the entire bit coin network.
Basically right now your are not mining with Bfg but monitoring the network. What ASIC are you trying to run?
Hope that helps.
Namnuta is absolutely right you are not mining and no hardware is listed in CGminer window.
Try this, in CGminer window type the letter "m" then the plus key "+" then "all" and hit return. it will refresh and list the hardware and info.
As far as I can tell, that would only work in BFGMiner. But there is indeed nothing mining.
