Im not even sure that is the right name but what do you guys think of the demo for this game, i personally liked it

Positives
Great fun to play
Superb Visuals

Negatives
Awkward controls
too unrealistic

i was wondering if anyone could help me with this problem ,

Everytime i try to play a game of call of duty 3 it says can't connect to all players and when i try to play a game of call of duty it says server connection error or something like that and all actions take about 7 seconds to respond.

Can someone tell me what's wrong and how to fix it
