If you haven't already updated your Skyrim I would recommend not. The latest update for Skyrim(Patch 1.2-http://store.steampowered.com/news/6894/ (http://store.steampowered.com/news/6894/)) supposedly "fixed" a bunch of bugs which had been released with Skyrim that were never fixed and yet it seems that this patch has brought out more bugs than before. With moonwalking/drunk dragons flying backwards, numerous Markath bugs which weren't there before, and for certain people it appears MR has been completely removed(Have fun with those mages).
