Exception when trying to view pending changes in team explorer

Question

Hi,

We use VS2012 and our TFS is 2010.

Everything worked fine for a while but then suddenly when trying to view my pending changes I got the following error:

System.MissingMethodException: Method not found: 'Void Microsoft.TeamFoundation.Controls.WPF.TeamExplorer.TeamExplorerPageBase.set_DefaultCommandHandler(Microsoft.TeamFoundation.Client.CommandTarget.IOleCommandTarget)'.
   at Microsoft.VisualStudio.TeamFoundation.VersionControl.PendingChanges.PendingChangesPageVS.CreateView(PageInitializeEventArgs e)
   at Microsoft.TeamFoundation.Controls.WPF.TeamExplorer.TeamExplorerPageBase.Initialize(Object sender, PageInitializeEventArgs e)
   at Microsoft.VisualStudio.TeamFoundation.VersionControl.PendingChanges.PendingChangesPageVS.Initialize(Object sender, PageInitializeEventArgs e)
   at Microsoft.TeamFoundation.Controls.WPF.TeamExplorer.Framework.TeamExplorerPageHost.Initialize(TeamExplorerPageContext context)

This happens only on my workstation. Also, using power-tools I can still check-in, just not from within VS2012.

I've tried reinstalling VS but the problem remains.

Thanks
