Have you tried replaying the ME1 romance scene? That's what worked for me. It was odd because I got Paramour and Insanity from Mass Effect 1, but Paramour II and Insanity II didn't pop for ME2, even when I replayed the relevant sections after the patch. Then I went back to ME1 and replayed the romance scene and final battle, and the achievements popped then.
My theory is that the progress for Paramour II and Insanity II (and probably Paramour/Insanity III as well) was not tracking properly for me before the patch. So when I completed the relevant portions of ME2 after patching, it counted "1 game done" even though I already had Paramour and Insanity. Then post-patch I went back and did the sections of ME1 again and it was able to count 2 games done at that point.
