Already a Problem: Can't download JQuery 1.5.2

Hi,

This is my first post. I am on a Mac (OSX) and am having trouble downloading the jQuery Core download - it goes to a page and shows up in a script.
I tried going in UI and downloaded (I think) the Core 1.5.1 not .2 and the UI of 1.8.
How can I download 1.5.2?
Thanks,
NJ
