the transaction is succesfull but nothing has yet shown up.
Bitcoin blockchain has been a bit overloaded last 3 days with currently 33mill byte unconfirmed from rising trading volume.
We have raised our mining fee a few hours ago to be on top. This will also help your old transfer stuck on the mining list on the child-parent principle.
As always its about transfer volume, mining fee and the miner privileges to pick the best first and a transfer broadcasted can not be changed or undone as long it already figure on the blockchain network and are on the mining lists.
