Error while importing SAP Router renew Certificate

Hi Gurus,

My sap router certificate got expired and got mail from SAP to renew, so I decided to renew it and followed link http://wiki.sdn.sap.com/wiki/display/Basis/HowtorenewtheSAPRouterlicense to renew saprouter certificate. All the steps were executed fine But I got below error while importing certificate from srcert file.

C:\saprouter>sapgenpse import_own_cert -c srcert -p local.pse

Please enter PIN:

import_own_cert: Installation of certificate failed

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

public key found

Please advise me to solve this issue.

Thanks,

Venkat
