Editing item definitions in VS Process Editor

Jan 9, 2012 at 2:04 PM

I've downloaded the process template from my server's Project Collection to the local file system. The XML definitions files can be opened fine as raw XML but if I try to open them using the Team Foundation Power Tools Process Editor add-in (Tools->Process Editor->Work Item Types->Open WIT from file), the open operation fails with message "This file does not contain a Work Item Definition".

I can open item definitions from the Microsoft Scrum and MSF Agile templates in the Process Editor without a problem. I can also open the SfTS item definitions directly from the server, just not from the local file system.

Please can someone let me know why the definitions are incompatible with the editor, and what I can do to fix it (if anything).  I'm using Scrum for Team System v3.0.4281.00.

Thank you,
