You may be right Sam. I know they were based on the same mesh and I kinda-sorta remember as you do. Unfortunately, the new product pages don't help. Neither lists dependencies and while the boys page only lists cr2 files, the girls page only list objs. To boot, the page for Matt and Maddie says 'If you already own either the Millennium Boys OR the Millennium Girls,' suggesting the boys were available separately. who knows :-) Would have thought the installer might complain also. Anyway, there should be a readme with the install that lists the files and their installed locations.
