We have an error in Campaigns.

After successfully creating and 'Test Sending' a campaign to either local users or contacts we receive errors.

We get: 'Error retrieving record. You may not be authorized to view this record' whenever we try to view 'Message Queue', 'Messages Sent/Attempted' etc.
We can however view the chart above this section which reflects the details of the Campaign correctly.

Any ideas would be welcome

Thanks
