User Profile

I am trying to compile an update to one of my existing apps, but I keep getting this error:Check dependenciesProvisioning profile "iOS Team Provisioning Profile: ***.xxxxx.***" doesn't include signing certificate "iPhone Developer: my name (xx43U4KZxx)".Code signing is required for product type 'Application' in SDK 'iOS 10.0'I checked my certificates here on developer.apple.com, and I have both a valid dev. cert & dist. cert.The dev cert. I created a few days ago (the old one had expired).I then downloaded it to my MAC and dbl-clicked on it.Also, I tried Xcode/Preferences->Accounts/"View Details"/"Download All"Neither seems to have worked.Is there anything else I need to do?Also, the provisioning profile for the specific app is still valid.Any help would be much appreciated!
