There is an error in the log similar to this:
This error comes directly from the Intuit Software Development Kit (SDK) and indicates that it thinks that the QuickBooks file is not registered.
There are two possible causes:
Cause 1. Register QuickBooks
Cause 2. Run the QuickBooks utility: "Repair File and Network problems". This will automatically open up the proper ports, etc. and the message should go away. More information on this QuickBooks utility.
