I have downloaded the demo for the Callie voice. It was working great as a voice from our ivr system. But since the demo has the nag message it was hard for our users to determine if it was what they wanted. I purchased the registration key and installed the key. Now the Callie voice sounds totally different. The nag message is gone. The other UNregistered voices, David sound the same with their nag messages.
Are there configuratin files that need to be added to return the voice to it demo sound?

There are no differences within the engine and / or data files that result from licensing. The only difference is the licensing reminder. Out of curiosity. What is the nature of the "total difference"?
