MSGPDocumentExchange error message

[gogetsome]

Hello, I'm having trouble with CRM integration with Great Plains and am trying to learn more about several error messages that are in event viewer. For example, when a new customer is added in GP the inetgreration does not carry the customer over to CRM.
I could use some help on what these error messages mean:
