Security error becos of TimeZone Download

Hi, i downloaded the timezone 1.3.7 version from the downloads section for my 1.3.7 zencart and when i uploaded everything, everything worked fine.
then i realised when i logged into the cart with my dummy customer account i get error_security_error and i cant log in. i tried the forgot password and it sends the password but it still wont let me log in. i tried registering a new user but as soon as you log out it wont let u log in again.

i have deleted the files associated with the download and i can log in now.
but i have the 3 yellow time zone error lines at the top of the admin (which is kinda annoying to see).

can someone tell me how i can fix this? i would like to use the timezone feature but if i cant can someone let me know what the code is to uninstall it from the SQL patches?

thanks.

Items are added to the configuration table in order - So if this is the lat item your added it should be last.

Backup Backup Backup FIRST...

Export the config table and open in a text or code editor and look towards the end and find "TIME_ZONE_OFFSET" remove/delete this complete insert and save.
import this to your DB

Hi! Thanks for your quick reply!
where do i find the configuration table?
its not /zen_cart/admin/configuration.php cos i dont see it there..

It is a table in the Database
