Unable to login after upgrade 1.9 to 2.0

I have installed and restored this site about 20 times now. I have installed exactly as described in the included ReadMe file. No matter that I do after the upgrade I am unable to log into the website. I am force to restore the site back to 1.9 everytime. I even went as far as just run the scripts all the way to 2.65 and still I am unable to log into the site after the update. Anyone else have this issue before? If so what did you do to fix the problem?

No errors to report. Everything completed as expected.

Also, I just noticed that I do not get an error when I login using my old admin account. The site doesnt see me as A) logged in or B) an admin. But if I mistype the user or password I do get a red failure message as expected.
