Hello guys,
Please, I was trying to restore an old wallet.dat (from 2017) but it get stucked, as you can see from the image below.
Is there anything I can do or is it definitely lost?
Is there a way to dump the private keys from the wallet via the command line? Do pywallet works with terracoin? I didnt want to try anything before hear your opinion/advice about it.
Thank you in advance!

.
Besides what Samspaces said you also can modify the short cut to the wallet and add -repairwallet to the end of the target and it will start the wallet and repair the wallet.dat file at the same time. It takes a while, but that almost always works.
Except only run it ONCE on that wallet.dat otherwise that can cause different issues with the wallet.dat file.
Thank you for your help.
I tried to create the -repairwallet wallet. The client crashed (windows error, program must be closed) and a new wallet was created as soon as it crashed. The wallet created was a brand new one, so it not worked.
