Hello,
Did you try with another web browser ?
Do you have web browser extensions ?
Can you see your 1000 crystals if you log on the F2P server (New Frontier) and open the cash shop interface ?
When did you top-up your account ? What was your payment method ?
EDIT : the subscription page seems to be broken again. I'll pass it to our CM, try again later
