If you'd like you could send me your wallet.dat and I could open them in my wallet, rescan the balance, and forward to your Bittrex account?

If that's not an attractive solution, you can still fill out a claim form here: http://ubiqsmart.com/coinswapclaim/

Wallet doesn't need to be synced to sign the address since it's not based on your current chain-state, but rather your private keys which are static.

DM me on twitter @Outragedhuman or @outragedhuman in UBQ slack, or here if you have additional questions
