Hello, I have an amount of this currency mined in 2014, but due to the lost blocks the wallet does not update, confirm the transactions received in the wallet, is there no possibility of recovering these blocks?
The new wallet client isn't compatible with the old one. What you should consider trying is downloading the new wallet client, waiting for it to sync, and then replacing wallet.dat file with your old wallet.dat. It appears they have a Telegram you can check with as well:
