@Enkidoh, IT WORKED!
I had tried this a few times over the past few days while getting errors. The error message said, "An internal error has occured (error code: Mandatory field state not found). Please retry later."
Mandatory field not found? Everything I entered had green ticks next to it. I filled out everything it asked me to. Let me look at this again.
I click edit next to the payment details and notice my post code and phone number are not added to the details. Once I put those in everything went through as expected.
Thank you again, @AngelCheese77, @Lirirawiel, @MilkieTea, @Jeeqbit and @Enkidoh! Your suggestions and helpful advice has got me back in Eorzea. :)
