Sorry for editing your post. What you had there may have been useless, but I'm not enough of a hacker to really give an accurate answer, so I removed it for safety. Any part of such information should never be posted publicly just in case someone has another part of it and can successfully hack together the rest.
Again, there's nothing we can do here about billing support, purchase issues, or related matters. Please contact Paradox's support directly via email:
support@paradoxplaza.comBest I can tell you is to verify the purchase has been processed through your payment method. My understanding is that purchases aren't processed until the transaction has been cleared.
