Affiliate Marketing Secrets

recently my Ps3 won’t let me play my downloaded games like mw2 and cod4. Its says I have to re-buy it or something and when I go to the account it was purchased one to re-activate my Ps3 for downloaded content, it says 2 systems have already been activated for this account. I let my friend get a DLC once for Mw2 but that was all. Now it doesn’t work. Is there anyway to de-activate ALL the consoles affiliated with this account? Anything will help, thanks 🙂
