I am having the same issue. i tried using another brower and resetting my EA account password and neither of those solved my problem. Its quite frustrating.

You need to reset the password on the linked EA account that account has the persona grumpyemperor (not Samnoks your posting on now) that EA account uses a outlook email
use the following link to reset the password https://signin.ea.com/p/web2/resetPassword then login on that EA account to fix the swtor account for purchasing
for future purchases, use incognito mode on chrome initially if you purchase on swtor.com to be sure browser cache and cookies is cleared
Thank you so much I got it fixed. Your're a legend for maintaining this thread.
