First off, thanks to OC for the great pool!  I've been mining at Suprnova for about 6 weeks now and have yet to successfully get Sammy's proxy mining working.  I believe I have the proxy set up correctly as it is receiving new blocks, but I cannot get ethminer to connect to the proxy.  All I get is JSON-RPC problems.  I suppose I just haven't yet found the super dumbed-down version of the instructions.  Thanks in advance for any assistance!

I am attempting to launch ethminer with this:  ethminer -G -F http://127.0.0.1:8546 --opencl-platform 1

What changes should be made if my proxy config looks like this:
