Thanks Bill,

I don't have any user-added datasets - so there's no problem there.
I can easily live with minor reversions back to default, so as long
as the major things are kept, I think I'll be OK.
The new features since my version will probably make up for any
small inconveniences.
Basically just wanted to know if everything got reset to a new
install condition.
I'll let you know if I run into any problems I can't overcome.

Joe
