Sorry, I thought you were having "general" problems serving-up files from your server.
This is simply what the compressed files were designed for, and I was guessing somehow the big/normal files are not being sent to the clients.
I don't think you would need the "advanced model support" fix for this pack, as they are old models.
You may be missing certain files, as Medor points out, you should have all the bonus-packs installed.
If you get no joy there are other U1 models packs.
OldSkool Amp'd will install a few old files you may be lacking, and is an exellent way of getting U1 content to work in UT.

YOU NEED THE FULL VERSION. not the lite version.
some people have problems getting it to work properly. I am guessing they never read the full documentation.
I've never had a single problem with it, and it made my UT far more functional.
