The best way to find your product is to do a search through your computer for either the email receipt or the product. Search for "silver lotto" or "shopper id" in quotes. This will usually bring up your order.
If you do not have those emails or information - if your hard drive has crashed for example, open a New Support Ticket with as much receipt detail as you can remember. Give order dates, the system you bought and your email address at the time - it's useful information that will allow us to trace it for you.
