Hi,
I installed MultiBit and created a wallet. I then created an account with slush's pool at mining.bitcoin.cz in my slush's pool account I created 3 workers. I then installed GUIMiner selected slush's pool as my server and entered my user-name and password. The Device selected in my GUIMiner is my Graphics card (Quadro 2000) and then I have the choice of selecting CPU Affinity, I have 8 cpus to pick. I click start mining but nothing seems to happen. My machine isn't crunching and my task manager shows no activity ? Also the GUIMiner gives me the error of IO errors - 1, tolerance 2

Anyone know what steps I may be missing ?

Thanks in advance.
