I am getting the follwing error

when I do the following http://localhost/DotNetNukeP 

Line 65:         ''' -----------------------------------------------------------------------------
Line 66:         Private Sub Application_Start(ByVal sender As Object, ByVal e As EventArgs)
Line 67:             If Config.GetSetting("ServerName") = "" Then
Line 68:                 ServerName = Server.MachineName
Line 69:             Else

Source File: C:\Websites\DotNetNuke_04.08\App_Code\Global.asax.vb    Line: 67

The whole situation is this. I am using Visual Studio 2005 and SQL Server 2000

I had an installation of dotnetnuke framework on the system located at C:\DotNetNuke which I didnt install, but when I tried to build the website it gave me tons of error so I thought that I will install a new version of the framework.

So here is what I did. Someone told me that I can have multiple framework so long as I create different databases and create different virtual directory in IIS. So I installed the new version at location C:\DNN , created a new table called Website and a new virtual directory called DotNetNukeP pointing to this location. When I went to http://localhost/DotNetNukeP It threw the error shown above for the config object.

I really appreciate all the help and I am new to this whole environment.
