VSDesigner Error

Hi everyone.

I'm using VS Pro 2008, C#. The project on which I'm having trouble was upgraded from a C# 2005 Express project, at which point the following error started occuring.

I'm connecting to a database via a designer dataset. When I upgraded, everything seemed to work, except that now whenever I attempt to configure, import, or generally change-via-the-wizard any table from which a cross-table reference starts (see attached image to see what I mean), I get the attached error message. This is not a compile time error: it's thrown by the designer the moment I click "finish" on the TableAdapterConfiguration Wizard (when it attempts to add the components to the dataset.)

The help button sends me here: Information Not Found, which is obviously no help at all.

The database is Access, 2003 *.mdb, OleDb connection. Sorry if this should go into Office Dev. :o

This is kind of an urgent situation, so please respond if you've got any idea what's I can do to fix this. I appreciate it.

Hoping someone can help,
Qu. :o
