New 1.0.4 installation hangs on admin login

[kaotix]

I recently destroyed my system trying to upgrade and didn't have time to try and rebuild it. I've removed the older version to reinstall as a new installation.

Upon completing the installation it says everything was ok and to login.
When I try and login the page either hangs and loads forever or gives me a 500 error.

Can someone please help me out to fix this as I have customers who want to get back online.

Thanks.
