Had the same problem. Go to the clickandbuy official website. Login with your stuff you used when you selected clickandbuy as your payment method. Once you're logged in you should be on the account page. If not click on the account page to get there. There is a big notification area right in the middle of the page. If there is any issue with your clickandbuy account it will tell you there. Mine was suspended for some reason so I called the number (very little waiting period) tech filled me in and I followed solution. After that I went back into my FFXIV account settings and was able to reactivate my poop.
