We are currently investigating reports from players receiving an error message when trying to make purchases.
For now we would like you to wait 24 hours before attempting to make another purchase. We will update you as soon as we have more information available.
Thank you for your patience.
As shown in my ledger, I haven't bought coins since more than a week and I'm still unable to buy anything.
I can't even choose to buy with paypal or my credit card, as soon as i click the button to buy coins, I get this error.
Oh and I already used both my paypal account and my credit card to buy things from SWTOR so there's no error there from my side.
