Since the time we released the theme and plugin, these networks may have made changes to the way you can secure your corresponding IDs and access keys.
These links may help.
CJ did make some changes to their site which now appears different from the one in our tutorial. This link might help guide you http://blog.cj.com/01182013/identification-it%E2%80%99s-everywhere
Developers ID - if you haven't done so yet, you can register for one here https://api.cj.com/sign_up.cj
PID - As lifted from the CJ support page: Your PID is your web site identification number and is unique to each of the web sites you have added to your account. When you apply links to each of your web sites you can change this number in your link code to have visibility as to which of your sites are generating commissionable traffic. You may add as many different web sites as you wish, depending on how expansive your program is. (Caution: Be very careful when making any modification to link code - the slightest mistake or omission will result in lost tracking.)
Advertisers ID - As lifted from the CJ support page, the AID is an Ad identification number which identifies a specific link and enables CJ to track creative performance as well as credit you when you earn a commissionable transaction. Because each link has a unique AID, it also allows CJ to identify the appropriate advertiser. (NOTE: The term “creative” is an advertising industry term that refers to display banners or text links.)
When a publisher generates HTML link code, the AID appears in the link code.
