Complicated Payment method

I changed my debit card becuase it was giving me some problems. Unfortunately I had my Adobe subscription enabled to my old card. Now when I am going to update the new card info on Adobe Payment Method, it simply refuses to accpt the card flashing the following text every single time. 

"Your data was not saved. Please try again. We apologise for this inconvenience.

Error Number: SYS_000006"

My debit card works all fine. But not on Adobe. I even tried my credit card.

Whats wrong?
