After purchasing the Guardian Armors, I am no longer able to do any further purchase. I keep getting Transaction Denied error. I have received the Guardian Armors and whatever that comes with it. Just that I can't buy any of the packs or CE. Don't OOO want my money now? :p
It MAY be a transaction limit or something like that. Its on wiki. You cant do big purchaes on newly credit card in short peroid of time (countermeasure for card stealing). You should contact support@spiralknights.com about your issue or use http://wiki.spiralknights.com/Support_Portal
