"no access to the digital certificate" - Trying to export my first iOS app from Flash - Help please

Hello

I'm trying to export my first iOS app from flash to my desktop / on the device (Flash Pro CC, Iphone5)

I followed the instructions on the adobe website to build an air app for iOS but on the last step it

doesn't export the app.

What I've done so far:

- Apple developer account

- creating the certificate + convert it to .p12

- app ID / Name etc.

- creating the provisioning profile from apple

- iOS Air app in flash (Only Text "Hello world" with a tween)

Now i have to load the certificates into Flash & enter a password (is it the password that

i entered in the certificate or from my developer account/ Apple ID password? Both didn't work at the end)

When i klick on publish in the last step than it loads a while but then i get the Error:

"no access to the digital certificate"

What is wrong? Can you help me please.
