I took another look at your WP installation, and the main cause to what you are experiencing is the Event Espresso plugin, this is not a conflict, it is just that this plugin requires a fair amount of resources and it even states that your server is meeting minimum requirements but you may face difficulties see the plugin menu (http://support.creiden.comwp-content/uploads/2014/07/espresso1.png).
I am sure if you deactivate this plugin you page would load normally.
However, if you insist on a refund (which we will be sorry for, not for the $55 dollars of course, but because our team is doing his best to satisfy all our clients no matter what), the refund process is issued through Envato Support. You can find more about it here:
Thanks for your patience, and sorry for any inconvenience.
