I just downloaded it from the megaupload link.
It sounds like you are familiar with the site, but on the first page below the main menu, to the right of the 'MEGAUPLOAD' logo with the arrow, there should be 3 coloured letters you need to enter into a text box (to prevent automated downloading or indexing) before you hit the Download button beside it. At the bottom of that page, below a fair sized Flash banner, should be the file name, size and description for the file.
The next page loads a table comparing the paid and free access features, and after a brief delay (45 second countdown timer), you should be able to download the file.
Or did you mean Platter's patch? Planescape-torment.org appears to be gone, but the 1.37 patch can be downloaded here
. There is also a 1.38 patch listed on that page, which may or may not overlap or conflict with Skardavnelnate's fixes.
The only mod I downloaded from Platter's site was one to max HP bonuses on leveling. That is also available here
as part of a 'Tweak Pack' (each component can be installed separately).
