I upgraded my windows 8 system to 8.1 yesterday, but since then the driver for my Killer Network card, from my Z87-G45 motherboard, been having issues. I downloaded the latest driver, but it gave an error when trying to install. I de-installed my older drive to try a clean install of the driver, thinking that I had my driver cd to go back to the old driver if anything went wrong. The latest driver wasn't compatible with my current operating system, and the older version from the driver cd wouldn't install either. Is a windows 8.1 compatible driver available? I would be able to download it on another device and transfer it via USB. Is downgrading to windows 8 possible without losing all of my files?
I hope to have fixed this problem as soon as possible.
