I'm trying to get my gpu to mine, but I'm getting some problems. So first, I followed http://www.newslobster.com/random/how-to-get-started-using-your-gpu-to-mine-for-bitcoins-on-windows
and did what it said to do. Once I got to the part where it tells you to start bitcoin -server using cmd. When I do that, nothing happens. When I try to run the daemon one, it gets stuck at "bitcoin server starting", and when I try to close it, it freezes and shows an error. What do I do to fix this problem?
