Retrieve historical data in Iteration Backlog

I have installed on Windows XP the Visual Studio 2010 Team System Beta 1. When playing around with the iteration Backlog workbook, I was unable to retrieve the Historical Data. The VB editor popup up with the following error.

When looking at the references of the workbook, it was indicating that there was an invalid reference for the workbook.

The issue was solved by removing the reference and add the same file (c:\program files\common files\system\ado\msadomd.dll) again.

Now I am able to Retrieve the Historical data again.
