In terms of your wallet being empty, the most likely problem is that you have selected the wrong option from Legacy/Nested Segwit/Native Segwit. What number did you old addresses start with. 1, 3, or bc1?
Yeah, I must have made on error there. But never mind. I tried one of the Ledger Chrome apps and I managed to transfer the funds out 'till I make the firmware update and reset to the Ledger. So everything is OK.
