Upgraded from 2.0.1 to 2.1, cant login

I just upgraded from 2.01. to 2.1 and now I cannot login to FreePBX. I went to http://www.aussievoip.com.au/wiki/index.php?page=freePBX-Admin and nothing there helped. What now. Clean install? what will happen to all of my setup if I do that? do I need to drop the database to do a clean install.

I think you need to use one of these 1 st. time out

then you can go in and set the admin password for GUIā€¦
