Just got a new debit card a few days ago since my old one was expiring; neither on the PSN website nor actually using the console will it let me utilize it for whatever reason; works fine on several other sites. It just says my card number isn't valid.
When I got a PSP and wanted to setup my credit card it wouldn't take until the info was exactly the same as the card info.
For me it was my name on the card: all caps and I think middle initial with period (I can't remember exactly, too many years since)
@tearhead: Yeah I tried that, didn't work either. Suppose I could try again with the inbetween address.
It worked! You're a hero sir. I wish there was a "worst answer" or "completely useless" button for @jking47 though :( Many thanks to the rest.
