Today, the development team has updated a display error that was occurring in Send Individually. It was apparent that when the add-in was loaded that some users would see an error at the bottom of the configuration window regarding "Error 512". Although this was just a display issue and did not effect functionality of the product, it was confusing customers. We apologize for the message appearing in the first place. The issue has been resolved in version 2.0.16. If you have purchased within the last 2 years and want to upgrade, you can do so by using the original link you received when you purchased. This is not a required upgrade.
