MDT 2008 Update 1 install breaks Deployment Workbench

[VinceV]

After installing MDT 2008 Update 1 I am no longer able to open the
Deployment Workbench. I receive a Microsoft Management Console has
stopped working error when I open the application.

OS: Windows Server 2008 x64, all patches are up to date
MDT 2008 x64, Update 1

I tried removing the update but it removes the application.
I tried to reinstall the original MDT 2008 but the file is no longer
available from Microsoft.
Clicking on Check Online for a solution... doesn't find a solution.

Any ideas?

Here's the error:
Microsoft Management Console has stopped working
Windows can check online for a solution
-> Check online for a solution and close the program
-> Close the Program

Wow... What a bear....

The fix is to collapse all of the nodes BEFORE you apply the update.

If you don't do that you may have the problem I did. To fix it I had
to edit the DeploymentWorkbench.mmc file.

Find <BookMark Name="SelectedNode" NodeID="9"/> and replace the 9 with
a 1.
<BookMark Name="SelectedNode" NodeID="1"/>

That fix worked for me.
