I tried to order tickets and was unable to on the ticketmaster website, said my code was not valid

WHAT! I joined the fan club 2 days ago, got my code which is an alpha numeric code 10 characters long, I have shared it with no one mentioned it to no one, how could this be? For those that successfully ordered, did you enter your code on the ticketmaster site where it said password? I tried caps first then no caps just in case, but I was shut out! I want to try again for the Denver show on sale in about a half hour, if anyone had a similar experience please let me know, and if anyone has any idea what may have gone wrong please let me know as well, 32 minutes to solve this! Thanks!
