Isn't AntPool like p2pool, in that your share payouts are coinbase? If so, remember that you have to wait at least 100 blocks subsequent to a given coinbase reward before any Bitcoin client will relay that output as a transaction. Are you sure you're using old enough coinbase to send a valid transaction?
If I'm correct, AntPool doesn't pay the users using Coinbase. All the Coinbase are sent to one address which makes it unlikely for them to be paying users using it. https://www.blocktrail.com/BTC/pool/antpool. I have addressed this above already.I'm sorry. I don't know how to check that. 
How do i do it? thanx
I don't use armory often but you need to check the number of blocks on the bottom right of Armory for it. How do i do it? thanx
