I topped up my account today with €50, which is the maximum possible. Not had any problem with this before.
However, after entering my PayPal details, the transaction appeared to go through. But then the top up page said to "try again" which I did. This second transaction also seemed to go through, again the top up page said try again. I checked my PayPal account and BOTH of the payments were successful. Then logged into game and saw that €100 of crystals had been added.
As I can't find a way to see how much is in my account on this website, it would seem the only way to find out if the top up has gone through is to log into game. I'm aware that topping up is possible while in the game but this would still take you through to the payment page with the same "try again" error.
I will be sending a ticket about this, it needs rectified urgently.
In the meantime, I would suggest people check their account, in game, before trying to top up again.
Is there no option to see your account total on the website, as gpotato had ? If there is I can't find it.
