Admin Demo is borken

[Steve Machol]

The demo only lasts 24 hours. We cannot fix a specific demo. You need to start a new one.

Can someone fix the admin demo. I have been trying to use it for 3 days.

Everytime I log on I get the error message

Your password is 186 days old, and has therefore expired.

I tried to change the administrator password and get error

You do not have permission to access this page.

How can I delete the admin password and make a new one like it wants me to?

Thanks.
