If you have the reference of one of your previous orders, sing in as if it you were to claim your pdf copy… All your pdfs (from all your orders) will be listed and you can download them again

If you don’t have a order reference number, write to customer support and let them know your details (your name, the e-mail you used to do your shopping, etc) and they will send you one of your order numbers so you can have access to them.
