i Can't hit the tie fighters that come after me, I shoot at them in the little box that is moving around them and it will not do any damage to them, what do i need to do to destroy them.. i am new to the game only been playing empire a couple of months and just bought jtl the other day, have played that first mission a dozen times, and it always ends with the time running out. and can't do any damage to the tie fighters..

Thanks Brian
