Please help. I have upgraded our board from 6.3.0 to 6.7.3 following the instructions here on the site, making sure not to overwrite any of the VAR*.cgi files.

After uploading, the instructions say to login to the control panel and select UPGRADE. When I access the control panel at /cp.cgi, I am prompted with a page that says Initial Setup and wants to populate the Environmental Variables. All of these are pre-populated with the correct information, so I advance through them. At the end it says to register a new admin account (even though I have one). When I click the link to register an account, it takes me to my board, which is currently closed for the upgrade. I am stuck and unable to either create an account or enter the old one.

Please help!
