Help With Auto Woodcutter

Hello, this will be my first post on this forum. I just recently downloaded the Sythe's Auto Woodcutter, and I need a little help and advice using it. I started off dragging the crosshairs onto the tree I wanted to cut, then used the eyedroppers on 2 different parts of the tree to get the color. Once I pushed start the cursor immediatelly went for the log out button. Why is this?

Thanks
