Today I got the blochchain wallet app and created a wallet. I then went to a bitcoin atm to get bitcoin. The bitcoin was confirmed to my wallet. I tried to send some bitcoin to someone but it would not even register it, I would press send and nothing would come out of my wallet or would show up on the transaction page. Now I am getting a "error: wallet.finalBalance must be a postive number" and the balance refuses to load. Help please?
