Hi, I bought the online play add on in the Playstation store for Resistance 3. It downloaded. It installed. I have a receipt. I have the email that I paid. I've restarted the PS3. I still can not play online. When I choose play on line, the game tells me to go to the store and buy it. What am I missing? Is there a "How to activate your online play pass for dummies" set of instructions somewhere?
