Under the last preview picture there is a red button, if you click that it takes you to the mediafire link.
This is the button you are looking for:
And when it takes you to mediafire you should see a link that says click here to start download.
Click it and it should start the download. Once downloaded unzip and place in your downloads folder.
I have never transfered something direct to my mediafire account, I know you can do it that way but I'm not sure how you then download it from your account so I can't help you retrieve it that way - sorry.
And thank you for the compliment btw
