I am getting this error repeatedly. Does anyone know how to get this working?

Would someone be able to walk me through getting set up for mining? I've never done it before. I can't find instructions anywhere.

I have no idea how to set up mining on my computer. My friends recommended GPU miner. I don't know how to install it, get it running, and everything related.
