I can't get the BFGminer to work on my Windows 7 machine. I've followed the instructions on <https://www.btcguild.com/index.php?page=support>. But when ever I run bfgminer.exe I get the following message at the top:

Waiting for devices; press 'M+' to add, or 'Q' to quit

I want to use my GPU, as I don't have any FPGA or ASIC devices yet. Can anyone help out?
