Error ITMS-9000 publishing game for iPhone

I’m trying to upload a game to apple store but always get this error:

ERROR ITMS-9000; “Missing or invalid signature.”

The steps i’m doing are:

1- Create development and distribution certificates, then download and add in keychain

2- Create 2 provisioning files, one for distribution and one for development, and download both. When i do double click on it, the xcode run but not do anything, can be here the mistake?

3- Publish the game on gamesalad and generate app

4- sign the app with game salad, select my provisoning profile and sign good

5- download the app in zip

6- Finally when i try to upload with "Application Loader” the error appears.

I’m doing something wrong with certificates? or i’m skipping something important? Please help
