Hi, I dropped my flatmates mighty mouse (I think it is anyway, googled it) and now it doesn't work. I only dropped it like 15 cm off the floor but now it doesn't work. It connected with the computer for like 10 seconds then went again and it can't seem to connect. It still shows a green light when you click it but the cursor doesn't move and it can't connect. The computer sometimes finds the device but can't connect. Have I broken it? Please help, my flatmate's away and I need to fix it before he gets back!!
