Can't log in Joomla Admin Section after Hot Start

The website is www.nflchances.com

I can give you the admin login in a private email if you send it.

This is the error message I get when I try to log into the administration section:

Please help

Is your database prefix wa89g_ like in that query from error?

Yes, the database tables are all "wa89g_" prefixes. Please understand that the content of the HotStart data shows perfectly well in the frontend of the website.

Note that I have tried the installation on a different user/account on the same server, and it also gives me the same error.

Please help.

I found the mistake. My admin password had the "!" character in it. I guess it doesn't like special characters.

Thanks
