I have purchased the Prime Location package for a vacation rentals site but when adding any text to pages it does not fit within the area outlined on each page. In addition, when trying to add a real estate listing page a fatal error message appears. Can anyone help?

Here is the error message:
Fatal error: Class 'RealEasteListingPageController' not found in
/home/sites/ManzanilloDream.com/public_html/packages/primelocation/themes/primelocation_/Real_estate_listing.PHP on line 88
