Hello,
We are looking forward for your fresh Joomla! installation to have a look. ARI Quiz component has been purchased by dozens of customers and noone except you reported such issue so we really want to investigate. This may be related to some conflicting components or something.
For customers to have a look at WORKING version of component we have 2 demo sites:
demo.ari-soft.com for Joomla 1.0.x and
demo2.ari-soft.com for Joomla! 1.5 so you can always see the component in action.
Since you contacted us via contact form and via forum we thought that forum is better means of communication. In this case we don't duplicate the message thread and other customers can have a look at this topic in case of similar problems.
Regards,
ARI Soft
