Right at the bottom of your page, on the black bar, is a little white suitcase.
Click on the suitcase, and that takes you to a page called 'My Uploads'.
You may need to click on the right hand column, 'Last DL' to show you your most recent download, and below that you'll see your other sold files in order of their most recent sale.
Alternatively, in your own portfolio, sort by 'most popular: all time'.
