Dear Josh,

Could I access your database? I've been found this error when there is a null value in a table. I would suggest reinstalling the database.

ASP.NET error after installation

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?
