[Unable to install plugin after reflashing USB with backup.]

I'm in the Same boat, unraid needed a USB replacement when I replaced the USB Key I can no longer update the my servers plugin i get the following error. 

 

plugin: bad file SHA256: /boot/config/plugins/dynamix.my.servers/unraid-api.tgz

[Unraid will not replace key.]

Hi, 

 

My USB Key went read only and I had to replace it. that is ok it was in use since 2018 so fine. 

 

however I followed the instructions to the letter but when I click replace key it just bounces back to the front page with a button saying finalise replacement key and do nothing when i click it. 

 

There seems to be no other option of support and don't want to buy a new license again !!! 

 

Thanks
