I don't remember if I'm extrapolating from an interview Moffat gave to clear things up or going by the narrative, but I think, at least in The Angels Take Manhattan, a complex paradox was created during the "landing lights" situation just to reach 1938, and, once another complex paradox was created to stop Rory from dying in Winter Quay, access to Amy and Rory became impossible.
