ther has Been an error with the fc store checkout. please try again

I just spoke with an assistant on live chat and was given no solution and was used as a test dummy so obviously no progress was made in the 45 minutes of my life that i will never get back, but thats besides the point. Im trying to buy fc points on the steam version of the game (ultimate edition) and even when i just click to buy a package of it says "there has been an error with the fc store checkout, please try again later." I better not get some bs copy paste response that solves nothing. Im just trying to spend money.
