Thank you marsbar . . . I deleted the folder and uploaded again. I don't think it uploaded right the first time, and having no idea what php was I didn't realize the mistake. I can now access install.php via the direct link [lenfante.com/globetrotter/install.php], but it still doesn't like my host name [Globetrotter@globetrotter.lenfante.com] nor the id and pw for either of my users.
The error message is:
The Following Errors Occurred While Installing Globe*Trotter:
The MySQL host, username, and/or password you entered is invalid.
BUT I'm so much closer than I was before! Support has confirmed the ids and pw's so I'm not sure what it is this time.
