So that it ask the 

.cer

 keyfile in your account again. You can create 

.cer

 file in your keychain go to 

Request a Certificate from a Certificate Authority

 and give your details that your mail id etc. so that it will create 

.cer

 file and in

developer.apple.com

 you can upload the 

cer

 file once you revoke your distribution certificate so that it will generate the certificate which can be installed in your system. 

注意，这里好像不能从别的电脑导入，只能是自己的电脑来提交自己的证书
