I was looking at all my files, and, with the exception of one, all files I have contain between 500-1500 individuals. The one that doesn't has a little over 5200 individuals.
I do keep the discs from previous versions, so as far as having version 16 goes, it won't be a problem.
So, it sounds like I'll loose information if I go from FTM 2009 back to V16?
The only trouble I have with V. 16 might just be on my end, but every time I go to "Create a book" in PDF mode, if I try to cancel the process before it's done creating the book, the program will stop responding. I've asked about it before and it sounds like a printer conflict of some sort.
