I just installed and configured the application. I have it on IIS 7.5, SQL Server 2008. I have given the group Everyone werite rights. I am getting the following .NET error but don't know how to correct it.

I would suggest doing a Google search, like this one, as this is an ASP.NET / IIS configuration issue.  There's lots of hits on that search.
