Did you send it when there was a wallet update & you were on an old client or when your wallet was still syncing ?
Try -rescan when starting the wallet & also try repairwallet in the FindCoin Console.
EDIT: Also did you send using the new FINDcoin or the old FINDyoucoin wallet ?
i send using findcoin wallet version 0.9.3. and it's sync well i think.
now my wallet stuck at 61093 of 70015 blocks, after i update my wallet.
maybe you know more node to add??
i'll try your suggestion. Thanks for that
Try opening your debug console and writing getinfo. If you see "protocolversion" : 90020 you need to update your wallet.
