Unless you have another EA account, your current account (the one you are posting with) is not linked to your GamerTag or PSN ID. That might be the cause.
If you haven't done it yet, link your Origin ID to your GamerTag or PSN ID:
Once you've done that, make sure your Skate share pack* (equivalent for Online Pass in Skate) is properly installed.
In some instances you may need to re-download and your Share pack code.
*The Skate share pack is a DLC for Skate 3 available for free in your console's store, generally listed under Add-ons.
