Well, I'm a new user, and the procedure did throw me a bit. You download the upgrade, then click on the installer. It installs 3.01 in a new folder (at least it did for me). However, the new library folder does _not_ contain all modules and adaptations, just the new/modified ones. So I made a copy of my old library folder, just to be safe, then copied the contents of the new one into the one from 3.0, allowing the old modules to be overwritten. There may be an easier way, but that worked for me. Irwin BPM773@...

Or does this upgrade replace 3.0? Thanks...Orlando.
