Light Wallet Back up Question

[Marketorder]

I backed up my Brain Key and downloaded the default.bin file. I renaimed the default.bin file is that ok?  Is that enough to backup my light wallet? Also what does No Balance Claims mean also what happens when I click on it?  When I click on Wallets in the settings I see No Balance Claims but when I first login it shows I have Bitshares but why does nothing show up when I click on Wallets in settings and I get No Balance Claims?
