I am on windows7 x64.  Installed bitcoin and the GUIMiner.  Running the ATi (AMD) OpenCL posted in the GUIMiner thread.

I have changed my bitcoin.conf (C:\Users\myusername\AppData\Roaming\Bitcoin) to have my username and password:


I launch GUIMiner and tell GUIMiner to launch bitcoin client as server.  I always get the "Problems communicating with bitcoin RPC" although I think I have set it all up correctly.

I even have launched bitcoin.exe with -server (and even --server) after a friends recommendation.  no avail.

I dont think port forward is an issue cause it is all local.

Anyone else experience this problem?  Any ideas how to fix this?

Thanks for any ideas, I am at a loss here.
There are several different types of Bitcoin clients. Header-only clients like MultiBit trust that the majority of mining power is honest for the purposes of enforcing network rules such as the 21 million BTC limit. Full clients do not trust miners in this way.

I had the same problem. It was the Windows Firewall. I thought I had it disabled, but when I went into the Windows Advanced Firewall settings, part of it was still enabled. Once I disabled that, all was well.

Good luck!
