I have released my last update to my app around a month and a half ago, today I tried to release a new update, and suddenly got "private keys are not installed". After some research I deleted all of my certificates, and created new ones by going to preferences -> accounts, but when I created them it created two certificates, one was grayed out, with my creator name, and status was "Not in keychain", the second one being the usual white color, nothing in status, and nothing in creator. Then when I try to sign my app and upload it, it gives me the same "private keys are not installed", even though when I go developer.apple.com into the certificates I can see my certificate, in addition to that if I go to Keychain Access, I can see the certificate I have just created right there, with an arrow opening up to show me that it also has a private key. I have tried to delete the certificate from the keychain after creating it in xcode, then install it from my developer.apple.com. I have tried to create a private keychain then request a certificate, nothing seems to work. Any idea what else I can try?
