I've got the same problem right now. If I try to buy gems with PayPal I only get a red error at the end saying "please try again later". That's about it.
I was able to buy gems in the past but right now it doesn't allow me to do so.
Can't pay with Paypal either. Same Story as told here before. In the past everything worked fine. Please let me throw money at you.
same here, tried 2 diff cards and paypal nothing works, get to confirmation screen then hit ok and get quick red message that flashes so fast i cant read it then it just goes back to buy gems screen
