No Miner can connect to RPC Server I'm new to this BitCoin, as in read about it yesterday started with it today. This technology has intrigued me to the level I cannot explain, its truly genius!

Back to my problem, I have a NVIDIA NVS3100 with approx 48 GFlops speed. I am using it to mine. I have taken part in different pools, but the problem is that miner is not connecting to the RPC server.
This is the error:

Could not retrieve work from RPC Server
CURL Return Value = 1


I'm using rpcminer-cuda made by puddinpop on Windows 8.

Would I have to make rules in firewall? or something like that?
For those who are having the same problem, please note that rpcminers are not supported by many BitCoin Miners, this was my problem.

I started to use GUIMiner and it accepted my first block just yesterday. No more blocks besides those yet, but well I'm just starting.

Regards

Thanks for all the help!
