If I were you, I'd do it all over again. Actually - I did do it today with my sites... Restore your backup (and the database) and go over the whole process again and maybe you'll spot your mistake. It's probably some minor thing you missed... And if you didn't install any addons (if it's a basic zc with changed template) you can use the files from this addon. If you did install some addons, i think the best way is to change your files manually and upload them exactly as it says in the guide.

Sorry i can't help you more...
