Can I just start by actually stating that nobody has asked anyone to pay for this plugin. It is free to use as much as you like. There is no payment involved, If anyone reading this can offer any assistance on how we can make this more obvious than we already do then we would welcome their input.

As to your problem - if it is caused by the same problem the previous users had then instructions by Dee in posts 5 and 6 above explain exactly what to do to correct things.

And if this IS the problem then let  me stress now that it is not of our making.  We utilise the jQuery tooltip script library that is both supplied and supported by your WordPress install. However, some theme and plugin authors supply alternative libraries that clash and conflict with the supported library. So we enable turning the proper one off to facilitate such usage. And no - we can not determine that such a library is being used - it is not that easy. We prefer to try and encourage authors to use the supported and supplied libs and for users who suffer such conflicts to also pressure the offending authors to do so for the sake of all plugins that try and stick to the standards laid down by the WP team.

If this does not resolve your issue then please do come back. A url to your forum page would be useful so we can review the output and console messages.
