In a separate tab from this page, go to my pastebin to get the new code.

Highlight & copy all the code in the box that says RAW Paste Data.

Paste the new code into its place & preview.

That should do it. If it looks wonky or you otherwise have problems, you can always go back to my paste bin and get the original code:
