Hi France,

I will try to answer your questions as best as I can. (caveat ---> (from a position of total ignorance, of course)

1. don't know
2. believe it is a complete version
   (... I have P4 and P5 installed at the same time with no problems)
   (when I add P6, I'll let you know if it works) ;=]
3. yes
4. yes, you can spend far more than that on other hobbies

re: P4 can't use P5 files?
It is often true that new features (i.e., files) that a newer version of software offers can not be used by previous versions.
IMVHO - It is not possible to make everything in newer software backwards compatible, n'est pas? (rhet) ;=]

re: P5 can't use P6 files?
Possibly ........... let's wait and see. ;=]

You're welcome!

cheers,
dr geep
