Hi @LeanneS, will she still need to use the other computer in the future? If I create her a new certificate, it will invalidate the old.
As the certificate is tied to a user and not to a machine, she can use the one issued earlier this year and install it on the new machine. If she doesn't have it around, I may be able to provide it for her.
Please let me know if you still want me to issue a new certificate.
