Hi..I'm brand new but excited to join in the fun...I was playing along in various shirmishes and Maps..learning how to do all of this..and after a short pause I came back to find that all though I could join all the online skirmishes and practice maps...I couldn't shoot anything????...I get pushed into the ready window and have to push on the continue botton to return to the game...but still no shooting available...any ideas from anyone???...Thanks... Joe
