I have a site workflow called "Create Moving Requests ". I edited it and when I tried to open it in Workflow Designer the following day I got this error:
Error retrieving config xml for activity 'Update Item' using adapter type Nintex.Workflow.Activities.Adapters.SPUpdateItemWithKeyAdapter, Nintex.Workflow, Version=22.214.171.124, Cutlure=neutral, PublicKeyToken=913f6bae0ca5ae12
I can't do anything with the Workflow besides closing it. I tried exporting it through NWAdmin and I get the same error:
Error saving workflow export file: Server was unable to process request. ---> Er

=126.96.36.199, Culture=neutral, PublicKeyToken=913f6bae0ca5ae12. ---> Object referenc

By the way the workflow works and runs without errors but I can't edit it.
Nintex Workflow Version: Nintex Workflow 2013 (188.8.131.52)
Any ideas on how to fix it?
