Hi guys, there is the things i met:
I had a wallet.dat file for FORCE-qt which containing 500.000 coins ready for running masternodes. I sent all the amount to a new wallet (in another PC) and CREAT A NEW WALLET ON MY OWN PC WITHOUT BACKUP THE WALLET.DAT (OLD FILE). And then when i send back 500000 to setup masternodes, i SENT IT BACK TO THE OLD WALLET ( WHICH WAS OVERWRITTEN), is there anyway i can recover it guys please? thank you so much for your help
