Your deposit will show up when your client downloads the block in which it was lodged, which is a recent one. There's a difference between the actual state of the block chain and how much of it your client downloaded. Check a service like blockchain.info. If there's at least one confirmation on coins sent to your address, you can spend the coins, even if your client hasn't downloaded that part of the block chain. (The transaction will show up when you dowload the block) Think of it as an absurdly slow way of downloading your bank history. Except actual ACH transactions take much longer.
