How to remove ads AFTER I bought the license?

I paid $39 for the ad-free version. When I got my registration number, I went into my site, updated the registration # in the admin advanced settings section, saved the settings, and reloaded the home page and the banners are still there. ARghhh...  Please help. I can't imagine that I paid $39 for no change....it should have removed the banners.

After using ad-free key for dolphin - footer must disappear at bottom. If not - try again. If it not help - you should ask boonex marketing about your license.

I finally figured this out. I went to the languages section and searched for powered by, and the langauge keys came up. I edit them all and deleted all the powered by options. I also deleted the FAQs (I don't want FAQs to my questions telling them about Dolphin.) Same with contact and about us.... I am changing it all to be personalized to my domain name.

drknight... Can you give the instruction how you do it?

Thank

Plz. contact boonex for such license related problems.
