I had a look at your site and most of the modules work (news, events) . I found just an error with search module which I post below.
Server Error in '/' Application.
error occurred during the parsing of a resource required to service
this request. Please review the following specific parse error details
and modify your source file appropriately.

About the issue that Quade mentioned, slow performance on backend - administration of sitefinity, what is your current experience on DiscountASP.NET?
