Best is to download from the new website as per blinks post, it is pretty well selfexplaining
-------------------------------
The first two links are dead now, moved to the new website.
Full Client Mirror is 4.9GB size and still works. Probably the torrent also still works.
When you get the game client downloaded, best way is to always start the game with the Chronicles Patcher although mir2.exe also works (but it doesn't check for recent additions, like today we got some tweaks)
