What happened to my wallet

I transferred 2 litecoins into my wallet and the transaction showed up. I then closed the litecoin app. When I restarted the app the wallet was empty and there was no transaction history. I backed up the wallet but I see no Restore function. What happened and how to I get my 2 litecoins back?

OK, found it! I was starting up the Litecoin testnet app instead of the real Litecoin app. Ha ha
