and here is the web.config

<?xml version="1.0"?>

          <add tagPrefix="GleamTech" tagName="FileVistaControl" src="~/FileVistaControl/filevista.ascx" />
          <add tagPrefix="GleamTech" assembly="GleamTech.Web.Controls.FileVistaControl" namespace="GleamTech.Web.Controls" />

          <add name="HttpPost"/>
            Set compilation debug="true" to insert debugging 
            symbols into the compiled page. Because this 
            affects performance, set this value to true only 
            during development.

The web.config seems correct, I have sent you an updated version of the upload DLL. It may fix the problem or at least you will see the actual function names in Stack Trace of the error message. Please send me the error message again.

Let me know.
