I have found out something that may be useful. SE took FIVE days to take my money from the $1.00 pending that they use to check validity of your account. From the 10th to today. If you have an original issue, like I had with a messed up pin where the bank put a hold on my card and I did not know it before trying to by crysta, it may take a long time to get processed by SE. In the meantime they will not allow another transaction to process. Actually that would be the card processor company because you can use the SE store for buying a time card. SE uses a different process for the two areas of transaction. Anyway my suggestion is to let it go for at least 5 days or check your banking to see if the charge is pending before trying again.
