I'm trying to eliminate a payment method. Your system for doing this is terrible. I don't want to 'Update Payment Method', I want to delete it. For some I can't. Why can't I see a list of all payment methods and choose what I 'd like to do with them, like every other bank/PayPal system out there?
Though I may not have stated it quite that way - I too ran into a hangup on this front as well, and it took a bit of thinking and poking around to eventually get a new credit card going for the current order.
Wasn't really intuitive and was certainly a frustrating experience - especially as it looks like I may have missed my "spot in line" to get the new PF2 books because it took repeated tries over a 24 hour period to:
a) realize I had an issue,
b) try unsuccessfully to update payment method, think I had it sorted,
d realize that I STILL had an issue, and finally
c) bang away at the buttons long enough to actually change it - and I couldn't tell you quite how I ended up changing it :P
Something for the web gurus to take a look at :)
