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=, 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

ror retrieving config xml for activity 'Update item' using adapter type Nintex.W

orkflow.Activities.Adapters.SPUpdateItemWithKeyAdapter, Nintex.Workflow, Version

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

By the way the workflow works and runs without errors but I can't edit it.

Any ideas on how to fix it?
