I come here for two reasons. The first is that i have completed all the required tasks to get Demo Master Calling Card and XP. Needless to say i got the Calling Card and the XP. Now I no longer have the card in my collection and I get a error on the Demolition Game Type Challenges section. I have all the tasks complete and the cards for them but now it says i dont have any tasks completed even though they are all unlocked and i have the playercard layer or calling card for the tasks. This is the issue. http://i.imgur.com/52Oko.jpg And the other issue is my brother lives with me and we can not party up or join the same server on Black Ops and yes we both have PC.
