AIR 17 to IOS publishing an .ipa "digital certificate invalid"

Last I attempted this was in AIR 14.0 and had no problems, I know this is an Adobe issue NOT an Apple issue as I'm getting the "digital certificate invalid" msg in Flash CC. I have a few questions as I must be inputting the wrong certificate.

Just to make sure, here is the workflow.

In the AIR 17 publishing window it asks for the p12 certificate. My question is which Apple generated certificate needs to be converted to p12?

I have the following certs:

IOS development

IOS distribution certs

then the provisioning profile certs

development

distribution

which one of the 4 certificates needs to be converted to a p12?

last question:

on the failure each time I receive the "digital certificate invalid" message

do I need to re do the certificates over again?

If so which ones?

any help here as I see Apple videos but NO Adobe on this.
