Recently I upgraded from windows 7 to windows 8.1 64bit, for the first while after upgrading my mouse was working fine without the driver from the disc, until now. My mouse is a Rude Gameware Fierce Laser Gaming Mouse v. 2 (Amazon link: http://amzn.to/1ppFNRG). Though I lost the disc; I look every for the disc and anywhere i could on Google/ forums to find the driver for the mouse.. I am wondering if anyone of the tom's hardware community knows where i could find the driver. Thank you in advance.
