***Solved, can't edit thread title I don't think.*** Hey guys, apologize if this topic has been discussed recently. Trying to use on file payment for my account but the "Continue" button won't work on the Mythic checkout page. Tried to re-enter the information and it said "The card number is not unique for the given user." Will go ahead and use a different browser just wondering if anyone had issues with the continue button or the like. Edit: NM, figured it out had to hit Manage Accounts button up at top right then I could change CC information in what was stored.
