ok let me understand...
the domain you have it is already been registered as a parked domain?
A parked domain is when you make your domain available for different advertisement to "park there" ( =shown through your domain). In this case, you should talk with your hosting support to unmark your domain as parked domain.
When you received the zip file from ABK they guide you to unzip the folder and upload the files to your server. Let me try to describe this...
Let's say you have received from ABK the chameleon.zip. You download it to your pc. Then unzip it (using win zip, win rar, 7zip, etc.). Following you have to contact your hosting company and give you instruction how to connect with ftp to your server. Usually you have to download an ftp client (for example FileZilla) and then connect to your server. More details about "how to upload files on my server" should be provide by your hosting company.
After you connect through ftp client to your server, you should place the files that are included to the chameleon.zip (look above, the zip we have extracted) to the http/www folder in your server.
No one born as webmaster so chill out
If you are still uncomfortable about uploading the files to the server, contact you hosting company and tell them "I have some file, that I need to upload to the server, how to do it?"
Feel free to ask anything here
