The serial number I had been using was not working, so they
sent me the new serial number (definitely serial number, not
activation number). The CD I have is for Version 2002, and I'm
really hoping this new serial number will work with it! The
reserialization email they sent indicates "RoboHelp Office, 5.0,
Windows, Universal English", so hopefully that work, and from your
email it sounds like I definitely need to uninstall and reinstall.
Thanks for the quick response.
