Redirect of domain causes NextGen to sorta fail

We are using this plug in for both standard galleries (images open over a darkened screen – click image to close), and for a header slideshow. Both of these functions (gallery and slideshow) worked fine prior to redirecting our domain to this newly-built site. I have poked around in NGG settings to no avail. denvertransitpartners.com is the site, site-wide header image should be a slideshow (all images are there and on the remote server) and on the What’s New page, that galler on the right side should be the “lightbox” effect. Any guidance appreciated. Thanks.
