Can't even get started

Well I was excited about this theme, but how to access it and where to start – very confusing.

Firstly when I try to login it keeps saying login with hosting company – I want to install on my wordpress in “Host Gator”
it doesn’t list them ? I also have an account with My Domain and I have signed in with them, but now my purchases are nowhere to be found.
I want to do this through hostgator and not my domain.

Then next some tutorials say unpack the zip file in your directory – I have downloaded a lll the files I was given, can’t see any zip files ?????

The video tutorial goes very fast and is too small to see properly – so I have this beautiful theme I can’t even get up on my wordpress.
It also says it can be installed for FREE when I purchase now – no emails etc have been sent to me outlining this.

Please HELP
