Hi missniceynice, I don't know in which country you are but it seems there are issues affecting age verification on some countries.
I am in Brazil, did the age verification a few times, uploaded my drivers licence, and even though I have credit card payment information on file I couldn't do that.
I opened a ticket that took 5 months to be replied (yes, 5 months) without a solution... it seems this type of issue is not supported for Basic (free) members.
I just gave up.... frustrating isn't it.
