admin log in problem

[kal]

hi

last night i was trying to change my admin email address, i managed to do it. i deleted the current one in my admin and added a new one.

this morning i am trying to log into my admin, it says wrong username and password.

i get my details (username and password) sent to my email address from bluehost control panel to make sure they are correct but still no luck.

any ideas?

thanks

for one of my webstores i'm getting this message when i go to my log in page:

0 DB_ERROR_NOT_CONNECTED
in:
[select * from znc_project_version WHERE project_version_key = 'Zen-Cart Database' ]
If you were entering information, press the BACK button in your browser and re-check the information you had entered to be sure you left no blank fields.

i don't know how this has happened,i haven't logged in for a couple of months.
