I just bought a new pc with also a new hard drive. I downloaded the whole blockchain and imported the Key into Etherum Wallet. But it still doesn't show me my ETH.
Etherscan saying to me that my ETH is there: https://etherscan.io/address/0x277a43260499e6045e0791171441d57d5d16c574 But my Wallet says my Balance is 0: Searching for a solution for like 4 hours. But didn't find anything :( please, Help!
