Hey Luke, if you are still there I have a question.  I am trying to set up bfgminer with my new BFL single SC.  I am not having any luck.  I had changed the driver to try to set up cgminer but couldn't figure out how to compile a configuration file to enable bflsc.  Anyway, I rolled back the driver because I read where you mentioned that.  I got the driver rolled back but I can't get bfgminer to work.  I haven't got anything to work when I try a conf file so I went back to none.  The best I got was it wouldn't accept any of my three mining sites saying the url was wrong.  It never did see any of my mining hardware.  Anyway, like I said I went back to the original without doing a conf file.  Now it won't start and I am not sure what to do.     
     Oh, I did do a bat file like BFL recommends but that is where it says my urls are wrong even though I can use the same three urls with cgminer with my video cards and fpga, just not the asic.
