May as well post this here instead of a new thread. Decided to try my DeathAdder again. I have downloaded the latest driver (v1.09) here and also downloaded the latest firmware (v1.27) here. The driver itself has installed fine, but whenever I run the firmware (it's an .exe file) Windows says the installation was unsuccesful and then just locks up Windows. Do I actually need this firmware upgrade, and if so, how do I install it without crashing Windows?
