Hi Marcia.
There is a folder mix up with the sample. I fixed the paths and am attaching one here for you. If you get an error connecting to your database, edit the Global.asax file and change the "localhost" to whatever you get there. Something like:
'-- SQL Server
DataLayer.DataSources.Add(New SqlDataSourceItem("", "MyInstanceName\SQLEXPRESS;integrated security=SSPI;database=StrataFrameSample"))
Hope it helps.
