I transferred iota from Bitfinex to my wallet in October. And at first the wallet displayed the balance but then it went to zero. How can I troubleshoot/recover my balance?
1) Get the latest wallet: https://github.com/iotaledger/wallet/releases
2) Try using different Nodes - Tools -> Edit Node Configuration Min Weight Magnitude should always be 14 or above. Curl Implementation can be tried both, Webgl 2 and CCurl
3) Generate a few address and re-attach them to tangle until your full balance shows up
