cylver: Hmmm. Ok - try one/both of these.
(1)
Bring up your Options window, go to Controls -> Window Keys
Scroll down until you see the row for 'Quest Helper'. Assign it a key.
Hit 'Accept' to close the Options Window.
Now: That key you picked should toggle the visibility of the Quest Helper Window.
I am thinking that it maybe got turned off by mistake. See if you can toggle the Quest Helper Window 'on' using that key.
Make sure the Quest Window still has the 'show Quest Helper' checked.

(2)
Rename your 'eq2.ini' file, and restart the game.
That will give you the official, default SoE UI.
See if the Quest Helper Window shows up. You might have to do (1) above.

shadow123:
(1) See (1) above - you can use that to assign a toggle key to the clock.
I THINK the game will remember how you have it set.
(2) By 'stat bar', do you mean the long, two-row bar of persona stats?
If so, bring up your Persona Window. There is a toggle for the two-row bar in the upper left corner.
(3) I dont know about the DPS stats. That MIGHT be a setting in Options.
There are a number of 'start button' mods out there that replace the big EQII button. One of these, for example, is by Goldi.
These often have a number of additional buttons on them, including a 'night vision' button.
