Okay, so this mod would not work on my Steam version of C3C that was installed in 2011. The text was all over the place, and the game would crash when I settled my first city.
Then I decided to start looking around....
As I said before, my copy of C3C was installed in 2011. I noticed that (for some freaking reason, thanks steam) the game had some updates. I looked at files, and for some reason stumbled upon the "labels.txt" file. That file was updated in 2015. There is also a script.txt that was updated in 2015.
I compared the two files. It turns out that the LOTR mod was one line short. Of course, not your fault -- this update is the problem. The update has a line that says "Unknown" between lines that are labeled "ping" and "host". I inserted this line into the LOTR labels.txt file, and now it works PERFECTLY!!
Again, this would be for steam purchases where your game was updated in 2015. I seriously wonder what they were thinking in messing with that file -- did they not realize what that would do to all the old mods?? I wonder how many mods could be fixed by just inserting this one line. This is the first Civ 3 mod I've installed, so I don't know the answers to those questions (thank you Civ 6 for sucking so much lol).
I hope this helps some of you out there! If someone could fix the mod itself that would be great, or I could upload the new labels.txt file if that would be better.
(NOTE: The game itself would not work on my win7 computer until I went through and unset the "read only" that is set for Civ 3 after install. After that, it would work. Hope that helps someone as well.)
