They really should go to something like an encrypted domain locked license key for paid versions of the script. That would eliminate all the problems.

Changing the line in templates/tmpl_uni/_footer.html to:

<!-- __boonex_footers__ -->

should make the footers go away forever. If you just remove the line, you'll get the... you've removed the footers without..bla bla bla error.
Well done, that worked brilliantly!
