I'm having similar problems. I've tried reading all I can, and I even went and got 7zip via web download as opposed to the Windows app store. That seemed to get me farther, but still I am stuck. I'm a noob, make no mistake, but other mods were pretty easy, even if I had to use other apps that 7zip wouldn't unzip. But ALL of the others simply needed placement into my regular override folder, and all was/is well. No problems at all. Also, does this site require a paid membership to view the NSFW mod pages? I tried finding them (including Natural Bodies) but I get an orange bar saying something about adult content. I have nothing blocked, AFAIK. Any advice is appreciated, besides "stop being a pervert".
