I have a new pc and want to access the ETH I had in my wallet on my old pc before and send them to poloniex. I have the keystore folder. I downloaded the current Ethereum Wallet (0.8.3) and it started syncing. I realised this would take a couple of days (like before) so closed it and instead ran:
geth --fast --cache=2048 --jitvm I also replaced the file in keystore with the one I backed up before. This has run overnight, in the meantime, if I click on "Launch Application" for EW, the balance shows as 0.00. Do I need to sync to be able to get my ETH?
