No buyer badge in your profile. for download the theme you have to use the original purchaser account.
Using the original purchaser account you can download your purchased theme from your Dashboard Download tab. Go to Downloads and download from there (Assuming you are loggedin in envato market).
Edit: @mgscoder types faster then me!
