When your browser is upgraded or reinstalled, the certificates
and cryptographic keys stored in it are permanently
lost. If you have a backup of your certificate in the
form of a .p12 or .pfx file, you can 'import' your certificate
from this file. Please click
here
for the certificate import procedure.
If you don't have a backup of your certificate, you
will need to apply for a fresh certificate. Please
contact
your RA Administrator for the same.
