Same here I couldn't extract all these files to one. Even when I did it manually, still there was a problem and this file was not complete.
Of course, after the start and dat.file change, there were no coins in the wallet. Should be 100K but was from 5000 to 12K depends on which file I used because, as I said, I had problems with this Mega file from Idaupdater.
Members suggested in this thread using repair wallet command in the console. After some time restarted wallet and almost all coins are back but still minus 10%. Not staking no matter what and only one connection.
Anybody running a masternode and getting paid?
