Nintex Workflow not in repository

Question

When I try to view a nintex workflow in Sharepoint2010, I get an error Error Occurred. Unable to preview workflow.
When I click edit then, I get an error: Error Cannot find workflow in repository. I get Sharepoint Designer can not display the item when I try that with Sharepoint Designer.

When I look in to the Sharepoint logs. I see this error:

(https://workspace.customer.com/_layouts/NintexWorkflow/Preview.aspx?WorkflowId=ba41a315-0536-474e-a719-aa5dc4ea8da9&ListId=00000000-0000-0000-0000-000000000000): Nintex.Workflow.NWException: Nintex.Workflow.NWException: Cannot find workflow in repository.

Does anyone has any suggestions?
