So... i went to the tower of mzark, got the elder scroll (after watching a walkthrough on how to do it LMAO), got the lexicon, went back to that crazy guy...went to the throat of the world, used the elder scroll at the Timewound...watched the vision, fought alduin, used dragonrend, then he swooped down and kicked my ass. luckily i quick saved the instant alduin started to attack. but when i reloaded to the quick save, alduin was stuck in mid air. even if i used dragonrend on him, he was still stuck. how annoying!!
so what i had to do was go to an earlier quick save when i was still in the tower of mzark puzzle, do that over again. luckily, alduin wasn't stuck anymore, and i got to kick his ass. anyone else experience this?
