.zip file of InFocus not uploading

I just installed WordPress. There’s nothing on my site yet. I bought a theme at ThemeForest called “InFocus.” When I try to upload to the WordPress installation at the website, the icon says “connecting” interminably, but never does upload it. I’ve gone to “Upload Themes,” and have managed to get the .zip file in the line where it says “Browse”. But once I press “Upload Now,” it just hangs forever.

How can I get it to load?
