HELP with adsense please!

I bought a site and went through all the pages to change all the adsense code from thier "pub-##############" to mine. I thought thats all you need to do since that identifies YOUR account. However, if you look at www.freecokecodes.com you will see "page cannot be found" where all the adsense shopuld be. Can anyone help?
