Should I reinstall Dimention Pro 1.5? I already have it installed and not even use it. And what are the expansion packs? Aren't they the same as they came with 8.5 or X1? Thank you, Vlada.

1.5 is 1.5  Don't need to reinstall if you already have it.

What I really want to know if the expansion packs are new or is Dimension Pro from X1 essentially the same.  I see no reason to install another copy of Dimension Pro itself, but if the expansion packs are different from X1, I guess I could install them only.  Anybody really know?

I downloaded the new expansion pack....and still have the one I downloaded a few months ago.  They are the exact same file size.  So I would assume they are identical.
