Looks like I need to change the usb key. I have another 16Gb key brand new. I found this procedure: https://wiki.unraid.net/UnRAID_6/Changing_The_Flash_Device
However, my circumstances are slightly different - the key was never installed because of the problem, so in the context of the link, I'm slightly concerned I will not have the option to replace the key, only to purchase or trial. Can someone advise?
Bought a key and attempted to install it, but getting Basic.key ... ERROR (4)
Any ideas? I tried searching for this error, but getting nothing in the forums.
