All is well with me now and I wanted to update you guys in case it helps.
I ended up synchronizing the clone via FTP to patch the missing files, for starters.
Was using
http://tinyurl.com/553cbw at Teach Me Joomla to generate the query for changing the password (which mysteriously wasn't working), but apparently something different about the new host (different version of MySQL?) the query wasn't working.
I ended up using the same page and copied and pasted - I'm not sure what it is - hash code for the password? into the jos_users table in MySQL and that successfully changed the password.
Y voila!
I'm in...
Hope that helps,
Tracy
