@Mishoku - Could you be a bit more precise on what you did? I also started Technic Launcher today to see that I had to input my saved account again. Hexxit also had lost all my set options and my world.
The world is still in the "saves" -folder as it used to, but doesn't show up. Same goes to the Sphax texture pack in the "texturepacks" -folder.
Where did you copy paste the world you had? I don't see any changes myself to the directory structure.
EDIT - Solution:
Found it. =) So the NEW location of the Hexxit folder is in "AppData\Roaming\.technic\modpacks\hexxit". From there you can find the "saves" -folder.
