In case you didn't know you should never install any games or tools in the "Program Files", because if you do that you can have a big problem in Vista/Windows7 with the folder(s).
You can ignore "Textures\_land_default.tga" and I think that's normal, but other ones are different and I think you will need to http://www.gamesas.com/index.php?/topic/1134570-morrowind-options-and-play-wont-work/page__view__findpost__p__16616928 Morrowind again. Before you continue please post your http://www.gamesas.com/index.php?/topic/1083121-relz-mlox-a-tool-for-anolyzing-and-sorting-your-load-order/ and the contents of warnings.txt here.
How else do you suppose I was to install it? I've never known any issues to arrise from placing a program within Program Files, since I always thought that that's the natural location they would be sent to. I am using Vista, and as for the warnings.txt, here's exactly what pops up when I bring the loader up.
Texture "Textures\_land_default.tga" count 3.
Texture "Textures\menu_thick_border_bottom_right_corner.dds" count 2.

As for loading mods, I actually don't use any mods, unless they've been preinstalled into the natural game, which I didn't think they were; though, if you mean Tribunal and Bloodmoon, Morrowind.esm loads first, then Tribunal, then Bloodmoon. Would changing the settings have been considered a mod in that sense? I did place the attack options to always use the "Best Attack", so if that in any way could have created this issue, I'll gladly switch it off and learn how to be not-so-lazy for once. To be honest, kind of entertaining to see someone running without any shoes, as though someone stole them right under his feet, and he just hasn't noticed yet.
