Cause: You are trying to subscribe to fields that doesn't exist in the data dictionary. This error can also be caused by subscribing to negative FIDs from your own custom data dictionaries. 

Action: Please verify if you are using the correct/updated or custom data dictionaries. You may use your custom data dictionaries but our Netprobe binaries include a set of data dictionaries that you may use in your MDM sampler configuration. You may download the latest Netprobe binary from this link for the updated data dictionary.
