Laser has a mind of its own, totally useless mouse

Summary: I got this mouse at the insistence of my Swedish friends, as I do professional gaming on PC. The first one I got had a laser that would randomly go off doing loop-d-loops (not sure how to spell that out) and making the mouse unusable.
Summary: I bought this mouse and used it for about a week. In that time it was amazing. Super responsive, fit my hand perfectly, and the weight system gave it good balance. I just tried to update the firmware and it failed. My mouse is now completely bricked and won't be recognized by anything.
