Sun Java System Directory Server - problem installing ssl certificate with Sun Java System Direc

I installed Sun Java system Directory Server 2005Q4 version 5.2.4 on a Windows 2003 server machine. To be able to enable SSL, I have to install a server certificate. I used the Manage Certificates in the console to make a request (obtained a CSR file) and then submitted to verisign to get a 14 days trial certificate. But I kept getting the following error when I tried to install it as a server certificate:

Private key not found

Either this certificate is for another server, or this certificate was not requested using this server.

I've spent quite sometimes on this issue. I will greatly appreciate it if somebody can help me out.
