Cubase Studio 4.5 update - missing HalionONE samples

Had to reinstall Cubase Studio lately. I have a boxed version of Cubase Studio 4. I did download the 4.1 and 4.5 updates from the download section, but i’m missing the new samples from HalionONE, which should be there (like the Yamaha SE90es piano, or the additional drum sounds). Where can i find the proper install packages? How can i have these samples again?
