Gone image template Real Estate Classifieds

Hello! I purchased a template Real Estate Classifieds at themeforest.net
All was well for a while. Now the site had problems: can not see images
Example: http://www.free-lanka.com/all/rent
Maybe I need to install the update. Just when installing template I not entered a license code.
Now my code is not accepted. What should I do now? When buying a template, I thought it would work, and no updates. In the product documentation it has been said that without updates it will work correctly.
