[Flash drive not detected]

I was updating my unraid server via the ui, but on reboot my flash drive isn't detected and I can't start my server.

 

If I reinstall unraid on my flash drive, is there a way to re-add my drives to the array on the new install while maintaining the data on the drives?

I was using a parity drive, however, I actually don't know which specific drive is mapped in what order in my array.

I did have a backup of my config.... but it was stored on my array and I don't know how to access it without having my server running.

[How long to recieve replacement key?]

Admittedly it’s only been about 30 minutes, but I assumed this would be pretty instant. 

I’ve checked all the folders on my email and haven’t received anything.

[How long to recieve replacement key?]

I initially setup my unraid server using an old USB and wanted to transfer my licence to this new one.

 

I have yet to recieve the email with the replacement key and can no longer run my unraid server.
