Cannot load project in TFS Project Dashboard

Hi

I am looking into the TFS Work Item Manager and Project Dashboard. I can connect the work item manager fine, but can't load our project in the Project Dashboard 

The error I get is:

---------------------------
Error Launching Dashboard
---------------------------
Dashboard failed to load project build01\PrivilegeGuard\PrivilegeGuard.
Would you like to remove this project from the dashboard rotation? 
You can always open the configuration dialog (by pressing F2) and add the project back into the rotation later.
---------------------------
Yes   No   
---------------------------

I have looked in the "My Documents\Work Item Manager 2010\ folder and there is a log file present (Dashboard-log.txt)

The error seems to be:

2013-03-25 10:27:53,097 [3948] [13] INFO  IRC.Gear.WorkItemManager.Common.UserSettings - User Settings file changed (C:\Users\devtvuser\Documents\Work Item Manager 2010\UserSettings.xml).

   at IRC.Gear.WorkItemManager.Dashboard.ProjectDashboard.CreateCanvasAndWidgets()
   at IRC.Gear.WorkItemManager.Dashboard.Dashboard.CreateProjectDashboards()

Do you have any ideas what this could be? 

Some extra info:

We use a customized workflow and have changed our work items.
I am doing this on a Windows 7 64 bit machine
I am a local administrator on the box
I don't have direct access to the database
I have chosen NOT to store settings in TFS, but changing this makes no difference

Please let me know if you need any more information to diagnose the problem,

Many thanks
Paul
