Simply, if you get this error:
---------------------------
Microsoft Visual Studio
---------------------------
Could not load type 'Microsoft.TeamFoundation.WorkItemTracking.Client.WorkItemTypeDeniedOrNotExistException' from assembly 'Microsoft.TeamFoundation.WorkItemTracking.Client, Version=9.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.
---------------------------
OK
---------------------------

Then you probably installed Visual Studio, Visual Studio service pack, then the Team explorer. Doing it in that matter overwrites parts of Visual Studio SP hence giving you such errors.
The correct way to install would be:
To fix the error now, just re-install Visual Studio 2008 Service Pack 1.
