I'm sure I'm doing something really obviously wrong here, but I have no idea what it is. Whenever I click the "Start mining!" button, it doesn't start mining. Both my GPU and my CPU are showing up in the Device drop down menu. I have an AMD Phenom II X4 CPU & an AMD Radeon HD 5770 GPU. Here's what my console is showing (I tried running it with flags and without):
