Zip Forms won\'t UPLOAD to THEMES

Hello, I looked and looked and saw nowhere that my download is only for Mac computers. I have an HP Windows 7 PC and I go to wordrpess, appearence/themes/add new theme/ upload file/ and it wont upload... The files i downloaded from Catch Themes is basically two folders. 1. says _MACOSX 2. simple-persona-pro Neither folder will upload, it just opens up the folders and shows several subfolders inside. I was really looking forward to this product as I have over 100 clients who want to use it. If I can't install it, then it's not going to work. But I'd love to find a solution. Otherwise IF this cannot be installed on PC computers, I wish I would have known and I'd like an immediate refund, please. Thanks JIM M
