I have had a developer account that had expired a year a ago, I am trying to test an application via sideloading into my iPhone, every time I try to side- load I get an email from apple like so; ,  You have revoked your certificate, so it is no longer valid. Certificate: Development Team Name: Taiseer Ashouri  Any provisioning profiles that include this certificate are no longer valid and must be regenerated for future use.  Best regards,  Apple Developer Program Support I have asked apple to delete my developer account, they say the did,,,, Any help

I only can sideload 3 apps with a paid dev account, when I try to sideload a 4th app it will replace the last side loaded app, please help.
