could not establish trust for the CA reply Help!

I am using portecle to generate a java store cert for JIRA. I created the keystore, create the key pair, generated the CSR, processed the CSR using third party CA. I then imported the root cert into Portecle. When I import the CA response I get "could not establish trust for the CA reply. The import cannot proceed.
Why is this happening as everything appears correct.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Have you installed the intermediate and/or issuing certs as well? You need to install the full chain. All trusted 3rd party CA's will have a CA structure similar to this.

Root CA cert
|___ Issuing

or

Root CA cert
|___ Intermediate CA cert
    |___ Issuing
