please help installing renewal

I purchased a PositiveSSL cert last year for a client’s site. I have since moved the site from the shared host to a VPS and renewed the ssl cert. I can’t seem to get the cert installed correctly. I get the following error: uses an invalid security certificate.

The certificate is not trusted because it is self signed.

(Error code: sec_error_untrusted_issuer)

I have deleted the ssl host and reinstalled but still receive the same error.
