If you are in the process of making a payment, and you click the submit button, but the payment appears to be taking awhile to process. DO NOT CLICK THE SUBMIT BUTTON AGAIN! Wait until you get to another screen, If it says, payment completed, then continue to use the site. If you come to a blank or bad gateway screen, click the user account link on the top of the site which will take you to your myaccount page. Look to see if the credits have been added. Then check the purchase history link and see if the purchase was recorded. If the purchase was recorded and the credits added, then the purchase went through. If not, then attempt to make the purchase again. If the system is still slow going from page to page, you may want to wait a few minutes for the site speed to increase.
