I'm trying to buy the Walking Dead season pass, yet every time I press confirm purchase I get a message that pops up saying 'An error has occured', while trying to add funds manually brings up the message 'The funds can not be added to your wallet (56)', with no explanation as to what 56 actually entails. I'm finding this incredibly irritating considering I've been at this for an hour now and the problem only started with PSN's new update. I've deleted PSN and reinstalled it, I've emptied my cart and refilled it, I've checked my bank details, bank balance, and connection to the internet. All my details are fine yet nothing I do is making any difference. Does anyone on here have any idea what's going on?
