Mike -
Funny you should ask, this is on both my live and development servers/portals! I have deleted the files and tried to reinstall and have had no success. Is there any records I may need to manually delete in the db? I took the same .zip file and loaded it on my personal website without error and when I tried again on my work site it failed with the same error.
I'm lost now. I don't want to reinstall the site but if I need to then I guess I have to. I didn't mention we were on 4.7.0 before and I upgraded our development server last week to 4.8.2 without error. Then all the sudden today the login stopped working on both sites.
Any additional help or ideas would be great! I'm hitting my head on a brick wall now 
Oh yeah, uninstalled the OpenId and LiveId and now cannot install them either. Tried installing a different module and worked just fine. Just the authentication modules.
