OK, so I'm having an extremely hard time my missiles to launch after a get a seeker lock with the A-10A. I enter air to ground mode, then switch to the Maverick with D. The seeker TV camera turns on, and I slew the piper to the target, lock it to the ground, and more accurately line it up until it snaps to the the target. I see the flashing cross on the the TV screen, but when I press alt + space, nothing happens, and I end up resorting to my cannon. Can someone please tell me what I'm doing wrong? Thank in advance.
