I have revoked my active development certificate ,and unable to create a new one, what is the solution ?
edit:
I followed these instructions
Generate a Certificate Signing Request (CSR) with a public key In your Applications folder, open the Utilities folder and launch Keychain Access. Choose Keychain Access > Certificate Assistant > Request a Certificate from a Certificate Authority. In the Certificate Information window, enter or select the following information: In the User Email Address field, enter your email address In the Common Name field, enter your name In the Request is group, select the Saved to disk option Click Continue The Certificate Assistant saves a Certificate Signing Request (CSR) file to your Desktop. The public/private key pair will be generated when you create the Certificate Signing Request (CSR) if you use the Key Chain Assistant to create the CSR. Submit the CSR through the Provisioning Portal to the Admin for approval. Click the Development tab Upload the certificate by choosing the file Click Submit You will be notified by email when your CSR has been approved or rejected.
