ADOMD.NET problem connecting to Analysis Server 2000

Hi,

I have the following environment:

Visual Studio 2003 / .NET 1.1
SQL Server 2000 Developer version, with Analysis Services.

I am having difficulty connecting to my cube from .NET. I CAN connect
to the cube using the included "MDX Sample Application", which (I read
somewhere) uses ADOMD.

When I try to connect from .NET, using this code:
Dim connString As String = "Data
Source=[server];Catalog=[catalog];Provider=MSOLAP;ConnectTo=8.0"
Dim conn As New AdomdConnection(connString)
conn.Open()

I get this error:

[COMException (0x80040154): An unidentified error was returned by an
external object to the XML for Analysis Provider.]

Can anyone help?

Thanks
