I apologize if this has been answered before, I couldn't find any answers through search.
I manage a large office building and use CA 8.0 to do remodel designs, and it has been a huge help over the years. Unfortunately, my old computer stopped working and I had to upgrade to a new one with Windows 7, and my old parallel port hardware lock won't work with it; so now I'm looking at upgrading to X6. I've downloaded the demo and have been using my old plan files with it succesfully (yay). However, the demo doesn't allow you to save, and I wanted to know if I could open files saved in X6 with 8.0
