Here is a link to 1.3b. This should contain the old changelogs if my recollection is correct about what used to be kept in the file structure (at least all of Soulmancer's work...not sure about 1.3a)
EDIT:Well...if they had a physical download this would be true....sorry but here is the link anyway.

I can delete the stuff below when/if you put a link at the top.
