So funny enough I saw another thread where someone asked a similar question and I saw you replied with "There are plenty of threads here on "switch integration" so I was sure to search here for that.
It looks like I did skip deleting the usergroup table. I did that, reran the install, and reran userfix.php. Now I can log in as administrator, but most of my users albums are gone.
In fact now it shows that my user album is 3000-someodd pictures, but if you go in you only see the ones that I have uploaded.
