So, I've been looking into the Fort Firemoth plug-in for TES III, Morrowind. It's stated that the plug-in is available for download at http://www.elderscrolls.com/morrowind/expansions/this link, however, only brings me to the main page of Morrowind. Can anybody help me with that?

(P.S: Sorry if this is the wrong category, I saw this one as the most fitting)

They can be found on the UESP http://www.uesp.net/wiki/Morrowind:Official_Add-Ons
