I can't buy anything from the store or download it for free
is always when opening shopping cart This event is no longer available?
Sounds difficult after the store's breakdown. Would just try again later.
Thank you for your answer
but time is not 2 weeks
Hm. Maybe you once had a promotional item in the shopping cart that is no longer available… Log on to a PC with your PSN account, go to the shopping cart and delete the content completely, then try again using the PS4.
