[CLIENT?] So my Pre-paid card won't work ? @Riot

So I just got 3 pre-paid cards (25$), first two worked wonders then the 3rd one won't add the RP and I get the "Invalide HTTP Reponse" message.

Can I get some help ?

I tried restarting the client 3 times, still the same problem.

EDIT : All settled It worked after a hour or so too, thanks.
