Hi,
I looked at your page and got an error message that says the gantry library isn't installed, so there is something wrong with the installation.
If you switch to another - non-gantry template, does the site appear in the browser? You want to make sure your Joomla installation is working properly, and isolate the problem to the lack of the gantry library.
Completely uninstall the Rocket theme template and the gantry files, then try reinstalling after checking out a few thngs.
JInstaller: :Install: Failed to copy file
Often indicates a problem with file permissions or a missing tmp directory.
Get Akeeba Admin tools and use it to fix your permissions. Check this out.

Library Uninstall: Manifest file invalid or not found.
usually indicates that you are trying to install an incompatible version. Check to make sure the version of the template you are using matches the version of Joomla.
