Good.  You're half way there.

Huh?  Which signed certificate?  The one that you had generated using the MS tool?  If so,
that's not going to work.  You need to generate a new CSR based on the keystore's private
cert and get a new signed certificate from your CA.  Then import the new signed cert into
your keystore.
