no.. u can delete everything but wallet and huntercoin.conf.. if your coins disappeared, it is because you was on the wrong chain.. keep your wallets tho, just incase you get back on the right one..

currently it seems the correct chain is at block 4600 - hardly any coins have been mined on the map.. so no one has "got rich" in this slight technical hitch

- i think ...

keep it up tho.. and everything will be ok
