Hey guys. I bought this deathadder V2 Pro Wireless only afew days ago. Perfect for me, because i'vd allways loved deathadder mouses, had them for 15 years. Been playing with the mouse, but then 2 days later, where i havent been playing, the mouse wont connect or ANYTHING. i use it so the usb dongle is in the "HUB" connected to the wire in the computer. on that setting 2.4ghz. NOW 2 days later, my mouse connect or ANYTHING. No power in the mouse. If i put the USB directly in the PC it "finds" the usb dongle. But the mouse will NOT turn on. WHAT HAVE HAPPEND. please help me.
