Help with getting rid of a mod

[sarabi26]

I don't really know how to change that day and night lighting mod into the normal lighting again, basically getting rid of the mod? HELP?

Your best bet will be to reinstall the game. Just uninstall it and delete the main folder then reinstall. Just be sure to back up any of your important files like maps or presets etc else where in the computer so you will not lose them and can replace them into the new install later.
Goodluck
