HI ive got an old folder on my pc that was from when i mined to nmc a long time back, how to i get a new wallet to see the coins i mined ?
If you were using namecoin-qt wallet and backed up your wallet.dat file all you have to do now is install the namecoin-qt wallet, replace the wallet.dat with your backed up file (on Windows \Users\<Your Username>\AppData\Roaming\Namecoin) and let it sync.
