Joomla Extension AS Menu - Item Support

I'm creation a company website (at this moment only on localhost) usign you 002046 template with this menu extension (on position 1) and I'm having a problem configurating the menu (as in the demo overview).

When I try to create a 2nd option on the menu (with the type AS Menu), I've the following error:

" Fatal error: Cannot redeclare class modASMenuHelper in C:xampphtdocscasadascorreiasmodulesmod_as_menuhelper.php on line 15"

How can I create the menu options to became similar to the one's you have on your demo?

Thank you for your help.
We are sorry, we are providing support to premium versions only.

Regards, AS Team.

Despite understand why you don't support the free versions, is a pity that there is no such support.
Without being able to change the menu to work, I do not know if it does what I want ( and if it's easy to manage, for instance). Therefore, I do not consider purchasing it.
Anyway, congratulations for your work. I do like you templates and extensions.
