I have been trying to connect with one of my friends that bought COD 4 just like me and we sometimes can connect on private games or to each others parties but most of the time now it will not allow me I get a connection error.. This also happens on Burnout Paradise City. Funny thing is that i can play with other people on random online games same thing with him we just can't connect to each other so we can play. I was wonderting if it has to do with ps3 updates?
