"Expired Code" message when attempting to sign in

Hi, i tried to purchase some gold with my coins and I found that you have to have 2 factor authentication to do so. So, I enabled the 2 factor authentication for the website and i got that email with the code and was informed that it was an expired code, not once but 35 times... I have more than 35 codes that ive tried and none work... so I disabled the 2 factor authentication and I'm finally logged in and have access to these forums, as I could not even log in to the website. How can I spend more money and donate if i cant spend the coins? Please, someone help me!
