Ok, I specify that all my past transactions appear in the "Transactions" of the new version Bitcoin CORE window, but the money is still 0, since we are still in the process of "re-indexing of the blocks on the disk ".
I've had this problem a few times - and the reindexing also failed a few times. I just stopped using Bitcoin core and imported wallet.dat into blockchain.info.
As long as you have wallet.dat your bitcoins are safe.
