So i got home today from work and my left mouse click seemed to stop working. I uninstalled the driver and reinstalled it automatically then using the driver software on the site, i have turned my computer on an off several times as well as using different USB ports. I also have my backup mouse in the same slots and it is working just fine. I am completely mind boggled how this happened without it being a defective mouse. I have had it for several months now with no issues. I have switched the profiles back and forth reassigned the buttons to different actions, and switched it from right to left mode. Still nothing. If anyone could help from here it would be greatly appreciated as i dont want to lose this mouse i do love EVGA and all of there products as 3 quarters of my computer is made up of them. Thanks for all of your inputs!
