Great question! Once you purchased the DSL Shopify Theme we sent you an email titled "Welcome to the family!" [access inside]" and there are steps in there on how to access the theme. If it's not in your inbox please check your spam/junk folder because sometimes our emails get sent there.
If you didn't get the email you can enter your email (same one you purchased DSL with originally) in this link and you will be emailed your username and can also reset your password:
You will then need to log in through here: labs.dropshiplifestyle.com
Once you are logged in then scroll to the bottom of the page and there is a section titled "Web Design". In that section click on "Shopify Theme Download" and the theme will download onto your computer and then you can upload it to Shopify.
That should work but if you still have trouble, let us know by sending an email to firstname.lastname@example.org.
