Go to your original email LW customer support sent you & click on the download link they gave you. That will take you directly to your personal download page.

If you no longer have that email then either you never received it & instead bought LW through a scam site who directed you to the LW Basic download page, else you deleted your email (if the latter then see below).

Send a PM to limenathan (click on link) to tell him your story & give him your payment details, date of purchase, credit card details, etc.
