Hi @Anonymous User
If there was no scratch card voucher code in the box to manually add to your account, then the new method that nowtv are now using is to electronicly upload the voucher code to your account automatically after you have set up and registered your stick on your TV screen.
Have you checked to see under My Account > Passes & Vouchers on here, if the voucher is ready to go.
Should your sports pass show active with the cancel button, then what happens if you try to watch any of the live sports channels on your new stick ?
Does it ask you to buy a sports pass or some error message pops up on your TV screen ?
