Error in importing SAP Router Certificate

Hello,

I am trying to import my SAP Router certificate with the following command

sapgenpse import_own_cert -c srcert -p local.pse

But I get the following reply

import_own_cert: Installation of certificate failed

ERROR in ssf_install_CA_response: (1280/0x0500) No certficate with your public key found

I have placed the srcert file in c:\usr\sap\saprouter\ntintel

any suggestions?
