Be sure to process you payment within an hour or you'll get a Session Timeout on the Payment Portal page.
If you have not put in the credit card payment, please check your "work in progress" queue to see if the filing is still in there, if it is still there, you most likely did not get charged and continue the payment process.
If you did put the credit card number in the system, DO NOT ADD CREDIT CARD NUMBER AGAIN. First, check to see if the filing is in your work in progress queue, if it is, then call the RRC at 512-463-6751 and explain your situation. The system may have accepted the credit card payment but failed to move your filing into the RRC Online System. If you file a payment twice on the filing, the fees will be non-refundable and credits will not be given for future filings.
