sorting posts

Hi,
i had a CODE to sort posts per drag and drop in the backend. it was working perfect. Now there came an error when i was working on the page, it said database error, the page was white, didnt load anymore for a moment, was back after a while but the sorting didnt work anymore. It was like it normally is.
But i need to have the dates beginning by january and ending in december instead of the other way around.
The normal plugin to drag and drop in the backend wasn`t working.
You have any idea what i can do? I really need to do it that way.

Many regards rixi
