Hi Andreas,

Are you 100% sure you installed the "Java Unlimited Strength 
Jurisdiction Policy Files"?

You can check if the jce policy file is correctly installed by opening 
the JCE policy manager in Djigzo (Admin -> JCE Policy)

Is the JCE policy correctly installed?

If you installed it did you restart Djigzo? (it need to restart after 
the install of the jce policy files)

Kind regards,

Martijn Brinkers
