I am going on my fourth day trying to get the Cutline theme into my Wordpress dashboard. It continually says there is no style.css folder. I first thought I had it figured out when my WinZip program unzipped Cutline with empty files so I downloaded another unzip program which successfully unzipped the files. I did successfully load another theme so I think I am doing everything correctly (although that one had a file called installer)
