If it's just one single file you're missing (water.j2b) your best bet is to ask around and see if anybody'd like to send it to you. You have the CD as it is, it's perfectly legal.
And yeah, you kinda need to upgrade to 1.23 in order to get the downloads here to work. The ones denoted with a Lori icon ( ) are 1.24 or TSF and won't work with 1.23. Just an advance warning.
