Invalid iTunes Order Number for FileMaker Go Promo
I just purchased the FileMaker Go few days ago (1/17) and would like to purchase the FileMaker Pro through the latest promotion for additional USD 149 only.
However, I made a mistake when I fill out the application form in the first time, I should choice USA as the region, not UK. Therefore, I left the shopping-cart and re-fill the application form again to correct my mistake (USA), then, I got the error message "A request matching this iTunes Order Number has already been submitted".
Now, no matter how I try, I can not apply the promotion. And the shopping cart is empty.
Can anyone tell me how to fix it?
