Just got them to work. Woot!
The zip file that the dude posted, has 1 folder and 2 files in it. Post the 2 files to your base EQ directory, overwrite anything it asks. Then what I did was then go into the spell effects folder, copy everything there, then go into your spelleffects folder in your EQ directory, and paste everything to there. Overwrite any that are there. Worked like a charm.
The first time I tried, I copied the folder and files, but it either made a new folder for SpellEffects, or something else weird. It didn't actually merge the folders, or put the new files into the existing SpellEffects folder in your EQ directory. Will find out next patch if I have to redo this if I ever run the launcher. Probably?
