Hi Steve,
I recommend using a local installation to test if Moodle has a problem in the future. You do not need a hosting account or domain to do so. That way you control the variables of the installation. Using an auto-installer is not reliable in many hosted environments.
FYI - Changing the subject line in a thread can be confusing. I have tried to follow this thread in my email, but have lost it twice when the subject changed.
