Thank you, I doubt its (1) or (3) as I used the same card to upgrade my account abour 15 mins before, only trying to get 1500L so that should be well within the limits, so I'm assuming the Exchange system is bugged.
Sigh, that, and the age verifcation system screwing up on post codes, looks like SL are not having a good day.
Oh, well I'll try again tomorrow - and if its still broke... errm, I give up and find something else to do I guess
