I purchased this several years ago (or maybe I was one of the lucky ones that got in on the official free download, I cannot remember) and cannot find it now on my back up disks. I also have a game of the year set of disks I got last year and THAT does not even have it?

So I am willing to buy it again for a few dollars. Can someone give me a DIRECT link to legally purchase this DLC for PC?

All the links I found so far in 1/2 hour of Google search are broken.

Even the Bethesda official site only had an XBOX version link (I want PC) ?

All the DLC's (except Battlehorn) are http://www.amazon.com/Elder-Scrolls-IV-Knights-Nine-Pc/dp/B000JGU0VE/ref=sr_1_28?s=videogames&ie=UTF8&qid=1319686286&sr=1-28

I'm not seeing a good download route, so I think I would recommend buying a hardcopy such as:
http://product.half.ebay.com/The-Elder-Scrolls-IV-Knights-of-the-Nine-Oblivion-Downloadable-Content-Collection-PC-2006/56004089&tg=info

ok, fount it, it was under the name "wizards tower" not Frostcrag. Thanks for the suggestions anyway!

I will ask this thread to be locked.

Darn, bedtime is near and I am leaving town (and my PC....whaaaa!!! ) tomorrow so I will not even get to play in the tower until next week, and then there is skyrim in a few days after that!

Locked per OP request as resolved.
