Hi. I wrote about gamesalad just to show what I was doing. I used only apple software
"
1.In your Applications folder, open the Utilities folder and launch Keychain Access.
2.In the Preferences menu, set Online Certificate Status Protocol (OCSP) and Certificate Revocation List (CRL) to “Off”.
3.Choose Keychain Access -> Certificate Assistant -> Request a Certificate from a Certificate Authority. Note: If you have a noncompliant private key highlighted in the Keychain during this process, the resulting Certificate Request will not be accepted by the Provisioning Portal. Confirm that you are selecting “Request a Certificate From a Certificate Authority...” and not selecting “Request a Certificate From a Certificate Authority with <Private Key>…”
4.In the User Email Address field, enter your email address. Please ensure that the email address entered matches the information that was submitted when you registered as an iOS Developer.
5.In the Common Name field enter your name. Please ensure that the name entered matches the information that was submitted when you registered as an iOS Developer.
6.No CA (Certificate Authority) Email Address is required. The ‘Required’ message will be removed after completing the following step.
7.Select the ‘Saved to Disk’ radio button and if prompted, select ‘Let me specify key pair information’ and click ‘Continue’.
8.If ‘Let me specify key pair’ was selected, specify a file name and click ‘Save’. In the following screen select ‘2048 bits’ for the Key Size and ‘RSA’ for the Algorithm. Click ‘Continue’.
after click to "continue" I receive error.
