I think you maybe some of you have self forked from staking too many inputs too quickly at one time or staking before the blockchain had completely downloaded into your client.  
Can you give me you deposit address and i can send 1 CAPT to it and you can report back if you get it or not.

My wallet shows number of blocks 1786150, last block 00:45 UTC Tue 28 March ( about 30 mins ago)

If redownloading the chain entirely from network, i was able to get around the 500 blocks with a bat file that closes and restarts the wallet every 10 minutes.  You can also close the connections to peers while the wallet is open, it will reconnect and continue downloading but i don't know a way to automate this, but it would work faster this way without having to restart the wallet if you a have a way to do this.   When you get to less then 10000 blocks its easier to just close the connections manually and at some point after 5000 blocks it will no longer stop after every 500 blocks and will continue to the most recent block.
