Thank you for your guidance , success !!!!
the original keyfile was purchased in 2013 and associated with my damaged USB pen drive.
I've never had a need to replace it, until now. So this would be the first time the USB key has been changed since 2013.
I've attempted this ;
"* To install your original registration key, you can either copy the key file directly to the config folder on the flash device or you can copy the original key download link from your e-mail into the Key file URL field on the Registration page of the webGui (Tools -> Registration)"
By adding the key file to new USB flash drive. What was missing what the "replace key" section until I deleted the trial key and replaced with the old key.
I was then about to use the automated process and get the email .
All up and going, thank you for your assistance!!
