Help - GUIMiner RCP Error

[chrismca]

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:

rpcuser=c
rpcpassword=c

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.

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!
