Assuming you bought Premiere Elements in a boxed set, it should have come with a disc with additional content on it. Install that and it should include more themes, etc.
Otherwise, this content may be hard to find. You are, after all, working with a version of the program that's over six years old, and the entire way the program works has pretty dramatically changed since.
Thanks for the response! Looks like the program was downloaded in 2011. I called customer support and they said the program downloads are available for 2-3 years after purchase on the adobe website. The program was not bought with a disc, it was downloaded online. Looks like since it's past the 2-3 year mark, there is no way to get those additional downloads. Unless you know of anything? Is there an Adobe store that I can contact, because those files have to be somewhere? This is for a company program, not personal, so I cannot purchase it really for myself.
Thanks for the help!
You may be able to find a used boxed/disc set on eBay or Amazon.
