Back in 2015 I purchased two keys and I am currently using one and have never needed to use the second usb.
I had a bit of a scare a few days back as my server was only intermittently reading the usb stick. (Cannot find device bond 0) error.
After a little playing around the usb stick is now currently working, although it could fail anytime.
Is there a simple way to copy my current configuration to my second usb which I have never used or updated from when it was purchased
