I just reinstalled my Ubuntu OS and had to reinstall Litecoin-qt. When I started it up it told me the standard info about having to sync with the last 7 years of blockchain. And of course as a new install the balance was 0. I grabbed the wallet.dat from the backup and copied it over to .litecoin/bin/wallet and restarted qt. Now I see the transaction where I received the coin back in 2014, but the balance still says 0.
How do I get my balance back?
