updated the old version, but why the balance is zero.
Did everything according to instructions. What could be the problem?
What do you mean by old version? Did you use the VoteCoin textmode wallet? Well that is not upgradable to GUI wallet. Or did you use some of the pre-alpha releases of the VoteCoin GUI wallet? Then you should be able to just flash the newest version over. If this doesn't help, you can try putting the newest GUI wallet in a separate folder and copy over just wallet.dat file from your old version to VoteCoin-wallet\resources\app\VoteCoin\wallet.dat
