Hi,
You can export to Ajax or Flash simulation with the Free edition, it only puts a watermark on output, everything is not disabled.
So there may be something wrong while creating interactive objects (mouse clicks, key presses, text typing or quizzes).
You can see a demonstration here: http://atomisystems.com/demo/interactive-objects-elearning-interactivity/
This demo also requires some interactivies from viewers while viewing.
You can also download the sample project that was used to create that demo, the link is right below the demo screen.
Hope this can help you,
Regards,
