Sorry about that joymax. The transaction c456b5e539eac6025fd6c2f4d45c55156c7e4876f4430108957dd01bcbcc87b8 should confirm as it is not invalid, it is just seen by the blockchain as a medium priority transaction due to the zero fee. Due to this I cannot resend the transaction as it will just result in you receiving the amount twice.

I am sorry for the wait, diggit it always meant to send withdrawals with a fee and has been corrected to do so. I will tip you a bonus on diggit for all the trouble and hope that it does not in-convene you too much.

UPDATE: Looks like it has confirmed now
