ok guys I've done a terrible mistake.
I changed my drk passphrase using a pass generat but misclicked and didnt note it.
Now there are 1000DRK stucked in my wallet and I don't know how to unlock them.
I have some wallet.dat backup, can I recover my DRKs?
I did something similar last week, though not near as much DRK at stake. The previously backed up wallet.dat files will have your previous passphrase encrypting them. As long as the address is in the backed up wallet, just restore it (overwrite the new wallet.dat in C:\Users\\AppData\Roaming\DarkCoin\ with the backup) and you should be good to go.
