I am not happy! as i cant remove the Branding [SOLVED]

I have purchased the Professional version which says I am allowed to remove your branding, I have edited the about us section and removed the built by Html Executable information but it still appears on the published file. Can you please let me know how to sort this out as I have a client waiting for this file and who is not very happy.

Thank you.

Ok I would like to say sorry about my comments above, as I have worked out how to remove it, and for who dont know just go to applications behavior and click on dialog boxes and you can edit it in there.
