we have no idea what you did and how but as you can see on http://pasteboard.co/2maJrjmU.png you got lot's of JS errors in console. These errors are obviously not related with theme. You must did something wrong on your end and that's why it does not work as previously.
What we recommend is to remove all theme files via FTP and the same way, upload files from package once again but this looks like your files are incomplete.
