I have got into it! I still can't see the dongle in files to make a back up! g

I have tried 3.3.8 and it come up with "Cannot load wallet:This version of Electrum, is too old to open this wallet. (highest supported storage version: 17, version for this file is 33)"
Any suggestions?

I have tried to use Electrum and it can find my Ledger HW.1 but says it needs a Firmware update from Ledger - but there is nothing on Ledger site offering firmware updates - only app for their current products. Also on my Windows 10 machine I can't see the USB drive in the file manager to make a back up - what I i missing?
Thanks to trying to help

Hi
I have an old HW.1 Wallet that has some Bitcoin on. I am getting no help from HardwareWallet as to how to access the Bitcoin - their site just says its a "Discontinued Product". 
Do I have to purchase a new Nano S?
Please can someone point me in the direction of post that might help?
Thanks
Geoff
