Brilliant!!Wow, finding these posts and my old account 10 years later is weird as heck!
Someone posted about this game and Im trying to source my modded xbox version to release it on the internet archive and I find the exact instructions on how to recreate it TYPED OUT BY ME!

Unfortunately good 'ol @Thagarr hasn't been seen in these waters since 2016....Hey Thagarr
That reference is not ringing any bells for me.do you know if anyone has a copy of that Mod Installer 3.14 or anything close to it?
Could be from before my time?
The oldest modpack version I still have available is this one:
http://piratesahoy.bowengames.com/potc/b11.exe
It's from back in 2004, I think, and is still very modest in what it includes.
Perhaps that might work for you?
Same other earlier mod versions can be found here:

Build 12 is also still relatively close to the original game (though less so than Build 11, of course).
Build 13 starts diverging though; by, amongst others, vastly expanding the worldmap.
