I started mining recently. My first payout was:https://etherchain.org/tx/0x334d5bb9949930fa292cb93451b3aff96957eec1c90c80818d5cf70b5fd1a7cc
When I start Mist, I click on Main Account (Etherbase), but the amount shows 0.0 ETH. Does it need to sync? Also, there is a note about incoming transactions not being displayed and it says I have to create a wallet contract to see incoming transactions. So I'm assuming I need to create a contract??? I'm confused.
