After installing InstantKB on a Win2K Server, I find that I'm receiving a typecast error in ASP with the following text:

"Cast from type 'DBNull' to type 'String' is not valid."

The stack trace reads as follows:

[InvalidCastException: Cast from type 'DBNull' to type 'String' is not valid.]
   Microsoft.VisualBasic.CompilerServices.StringType.FromObject(Object Value) +616
   InstantASP.Base.IO.Configuration.GetOption(String OptionName) +110
   InstantASP.InstantKB.Globals.AppSettings.ConnectionString()
   InstantASP.InstantKB.Controls.CategoryDropDownList.ReturnUserNodeData(String sNode)
   InstantASP.InstantKB.Controls.CategoryDropDownList.RecurseNodes(String CallBackNode)
   InstantASP.InstantKB.Controls.CategoryDropDownList.OnLoad(EventArgs e)
   System.Web.UI.Control.LoadRecursive() +35
   System.Web.UI.Control.LoadRecursive() +98
   System.Web.UI.Control.LoadRecursive() +98
   System.Web.UI.Control.LoadRecursive() +98
   System.Web.UI.Page.ProcessRequestMain() +731

This install is using a remote SQL server, I've confirmed the connection string is correct and that the two SQL scripts executed properly (the database, tables, and initial data all appear to be present), but I can't seem to get it to work properly.  Anyone have any ideas?
