Purchased 5.62 coins from ThaddeusB last night around 12:30AM central,

He gave me this tracking number  https://blockchain.info/address/12A4Zz28AZKptJLLYkcbwrvNy6YbicSv8Z

the coins have to show up in my wallet, my wallet has not been updated in a long time could this be an issue?

anyone have any ideas why they are not showing up yet?
