I've looked about for any workarounds or even mentions of this glitch and I've found nothing, sadly. If you're not picky, you can have someone with Skyrim on PC just advance you through the quest and conjure you up an Elder Scroll. I'd be super totes happy to do that for you, so that this way you don't have to mourn 120+ hours of wasted time and a LOT of sacrificed goats to destroy Bethesda.

Oh, but to do that with the PC and the console and all, you'd have to find someone with a Skyrim on PC that only has up to the same patch as you do, or you'd have to go and re-install 1.4 since most people are using that I imagine.
