Error on MPS at Initialize Hosted Email 2007

Hi everybody, i'm using the HMC 4.0 method and no problem so far except this one :

When everything's fine, we follow this procedure [8-|]

<div class="HEADING">Configure Hosted Exchange Provisioning</div>

In this procedure you will use the Deployment Tool to initialize the Exchange Server 2007 namespaces as well as configure some security and registry settings. This is done by installing everything under the Exchange Provisioning Configuration node in the Deployment Tool.

<div class="INSTRUCTIONS" style="display: block;"> <div class="INSTRUCTION_INTRO">Procedure DWHE.99: To configure Hosted Exchange Provisioning</div>

In the Requirements Status pane, expand Hosted Exchange, and then right-click the Exchange Provisioning Configuration component.
Select Install all in this group.
Click Start Deployment to start the execution of the selected procedures.
Monitor the deployment session on the Install Details tab.

</div><div class="INSTRUCTIONS" style="display: block;"> </div><div class="INSTRUCTIONS" style="display: block;">My problems is that during these steps i get this error [:@]

I don't have enough experience to find out the problem, the error is not really explicit either, talking about "namespace", i truly don't know where to look and what to look for.

Any help would be really appreciated [:D]

Thanks for your time[;)]

Finally found it.

Problem was a component not installed in mps deployment tool...because not specified in the procedure...God helps us with Microsoft [:D]

Thanks for your time.

So what was the procedure you had to follow to fix this? I have this exact same issue and am getting nowhere with MS Support.
