cannot get any custom interface to work!!

[Endeavour]

well, 4 hours now trying to get both profit ui, and the horizontal journal interfaces to work, but they wont.
i went thru the install steps very carefully and no matter what i did, neither of them worked, eq2 ran in default appearance like day one.
is it something with vista? when i tried to extract the files with winzip, i get a "cannot extract to..." message on all of them, and the self extractor thats built into this thing extracts the files to the folders created in the UI folder, but everythings in the folder, not just the xml stuff.
so just **** it at this point...what the hells going on?
i have it running just fine on my 2nd pc that has win xp pro, both interfaces, but this new one here with vista i cant get anything done.
why isnt there a self installer for the profit ui and such?
