I am just getting started with bitcoin, and am running into problems already.

I have added both the bitcoin.exe file and the entire folder of guiminer.exe into Comodo Firewall/Defense+ as "Trusted file" but the GUIMiner just appears to stick to "Connecting...".
I have setup the correct path to the bitcoin.exe-file and have setup the username/password (which can't be changed afterwards, as it seems?).

I currently have set 2 miners, 1 on my GPU (ATi-HD4350) and one on my CPU (i3). In the summary they are both at the status "Connecting...". I have selected "Generate Coins" on the bitcoin program, and the fan on the GPU runs faster if I check the box while it slows when I uncheck the box, so it appears to be working...

The Bitcoin program also shows "1839 khash/s" in the statusbar, but only showing 1 connection, and the accepted column on the miner remains 0(0).

What is awry here?
