The Jazz 3 demo is not only unofficial, it is downright illegal. I suggest you read the JCF guidelines. They state that discussion of illegal activities is prohibited. Jazz 3 is an illegal activity. Since the demo is unofficial and illegal, there is no support for it. If you want to use an illegal unofficial demo, you have to accept both the legal and technical responsibility and also the fact that you are breaking the law. Please do not post things like this again.
