If your contract is waiting for payment, you may not have sent the correct amount of money.
Please follow these instructions to check that you payed the correct amount:
Go to your Purchased contracts page: http://console.pool.bitcoin.com/purchasedcontracts
Click your contract, then click "Pay with Bitcoin"
If your contract is waiting for confirmation, please wait a few hours. During high network congestion it may take a while for a payment to confirm.
If it does not confirm after one day, please email pool@bitcoin.com and we will try to include your transaction in the next block we mine.
