Hey i know what makes the withdrawal failed. It seem to be a must for player to input a 64 character payment ID when making monero withdrawals. Can i suggest to FJ? Seem it is a must for payment ID, why don't your site prompt players to input the payment ID and do not allow withdrawals to be submitted without a payment id.

btw, withdrawal is solved but my first withdrawal of 1 XMR is still missing. =p
