i enjoyed the campaign  but it seems i am always having trouble with playing black ops online......i tried to get help form activision but they were of no use.They persistantly told me that my problem was that ididnt have the correct ports open to play the game online. which i found strange because i have no problems playing any other games online.i actually had a tech support person from my internet provider (time warner cable)come by the house and they said all ports were open and i should be good to go..........sure enough it is still a bother to play the game online.........anybody else having these problems?
