Getting an error in CR when attempting to instantiate unmanaged code

[Rod]

I've upgraded a Visual Studio .NET 2003 app (C#) to Visual Studio .NET 2005.
It is a WinForms application, and it uses Crystal Reports 11 Release 2.
After going through the upgrade process with the upgrade wizard, I tried to
run the app and I got an error in the InitializeComponent() function of the
WinForm (there is only 1 WinForm in the application). The message told me
that I had to add what is known as an MDA assistance into the app.config
file, which I've done. The error is of type pInvokeStackImbalance. I've
added the relevant XML to the app.config file and now I'm getting the
following error message on the InnerException:

System.TypeInitializationException was unhandled

Message="The type initializer for
'CrystalDecisions.ReportSource.ReportSourceFactory ' threw an exception."

Source="CrystalDecisions.Windows.Forms"

TypeName="CrystalDecisions.ReportSource.ReportSour ceFactory"

StackTrace:

I've removed the CrystalReportsViewer control and put it back on again, but
I still get the same error message.

So, what's wrong now?
