I have the backup wallet.dat can I redeem the coins without problems after the hardfork?
The hardfork has already happened, you should be able to download our new V3 wallet and import your wallet
I've downloaded and installed the new v3 QT from scratch. It just doesn't sync. You need to fix that shit, guys.
EDIT: 0.05% progress increase per hour of syncing headers. Couldn't make this up.
