When you try to insert a new Credit Card in Microsoft Dynamics NAV 2013 appears the above error message.

Encryption key was not found

Solution:

  1. In the Search box, enter Payment Services Connection Setup, and then choose the related link.
  2. On the Actions tab, in the Encryption group, choose Generate Key to generate the encryption key that is stored on the Microsoft Dynamics NAV Server.

Experience: I suggest you if you use the Generate Key functionality to download and store in a secure backup the key generated using the button Download Key on the Actions tab, in the Encryption group.
