TFS Integration tool - Unable to load one or more of the requested types

Hi

Running the migration from TFS service to local TFS server 2012 , i get this error constantly on a specific change group.

Application Information: 0 : Microsoft.TeamFoundation.Migration.Shell, Version=2.2.20314.1, Culture=neutral, PublicKeyToken=31bf3856ad364e35
Application Error: 0 : A failure occurred while trying to load the C:\Program Files (x86)\Microsoft Team Foundation Server Integration Tools\Plugins\Tfs2008VCAdapter.dll Plugin:

I read about different solutions but none seem to work for me. How can i fix it? Can i skip this specific change group to verify maybe this is the problem?

Thanks
