There was nothing wrong with it. I just had my controller on the default of 2players instead of 1player which why I couldn't install the game. It was because I forgotten to unplug my fighting stick after finishing Green Lantern
There's no need to friend them at all. FEAR 2 has a famous PS3 chat that boosters use to get their XP. Everyone in the chat all knows how to boost it. I can just send it to you (yes I still kept the chat lol, everyone does). The chat is over like 2-4 years old and people just be logging into the sessions to see it anyone is boosting. You'll need to get friendly with these people. If you don't know how to boost they will help you by teaching you or you can watch what to do.
Right now I just log in the chat and it's only 4 people online in it ATM. More people log in it over night usually.
