Can someone tell me if my sync are lost forever? I attempted to send some sync from my mac wallet earlier today to bittrex but i did not realize until a few hours later that I was using an older mac wallet (downloaded 3 weeks ago). After contacting bittrex they pointed out that the txid isn't in the blockchain, which I checked the explorer and its not there. And now after updating to mac wallet v1.0.4.0 its stuck synchronizing on block 94391. the wallet transaction details has it confirmed: Status 184 confirmations. Did I just lose 1 sync? Any help would be appreciated.
First make a backup of your wallet.dat file in a safe place!
Navigate to Help/ Debug Window / Console
In console type "repairwallet" without the quotes.
If this doesn't work, you may have to re-download the whole blockchain again - I have had to do this on a couple of occasions. Your SYNC should be fine though.
