So... Enderal requires the original version of Skyrim to play, but it would appear that Steam no longer has that, and it's missing from my library too. Am I hooped, and can't play it now?

Edit: It seems that the original version IS still there, but it won't show up in either the store or my library. I had to go to the Enderal page on Steam to find a link where I could install the original version.
