This error indicates that the API Key found in the Luminate Online plugin within RE does not match the Luminate Online API Key. To resolve this we will need to find the Luminate Online API Key and enter this into the options tab of the Luminate Online plugin within RE. If the Luminate Online key has been updated recently in LO, support will need to be notified to ensure that this Key is updated in the service bus that sits between Luminate Online and The Raiser's Edge.
