I have been trying to join IMDB Pro for 2 days now. Upon clicking the continue button to reach the final step of joining, I get an error message that reads, "Sorry card Required." I have tried several payment methods and the same prompt appears after each payment method. This is EXTREMELY frustrating, especially after having joined amazon prime exclusively for the IMDB Pro attributes. Please send me a solution to this problem because I do not want to go a third day wasting time wondering if I will be allowed to join or not. This is ridiculous.
