I'm new to Pc so forgive me, I have been playing and using nexus mods for about over a month now, but this afternoon I booted up my pc and went to download a couple performance mods through the site. my nexus mods window booted up, and downloaded the mod, but refused to display on my screen. I tried restarting my pc and rebooting application, but to no avail.
