MBP Will go to Sleep and Console Message: Throttling Respawn 10 Seconds

Question

First, my MBP will not go to sleep. I have done an Archive and Install and that didn't fix it. I looked in my console and there is this repeated message that happens every 10 seconds.
12/7/08 1:28:42 com.apple.launchd[1] (com.x3.x3daemon[249]) posix_spawnp("/etc/.x3/x3d", ...): No such file or directory
12/7/08 1:28:32 com.apple.launchd[1] (com.x3.x3daemon) Throttling respawn: Will start in 10 seconds
I have no idea what is going on and would love some help.

Answer 1

I close the screen of the MBP and I wait for a moment
or two for the blinking (not entirely blinking but
the typical sleep-mode lighting that apple portables
have) sleep light to come up but the computer will
not go to sleep. This worries me because the hard
drive doesnt go to sleep either and the machine is
kept warm all the time it is supposed to be sleeping.
Additionally, when I wake up the computer by opening
the lid up, the light dims and remains lit without
nothing happening maintaining a typical black screen.
Then, I manually press space bar (or any key) to wake
up the computer and it gives me the blue screen for
two to three seconds. Then, it brings me back to
where it was left. And I find the computer in a state
where it is too warm.

Shut down MBP. Disconnect AC Power. Remove Battery. Hold Power Button for five seconds. Apply battery. Connect to AC and try again.
Reset PRAM:
From a cold boot, off, hold the P and R keys and the Option and Apple keys, all at the same time. Wait for 3 chimes and release keys.
Make sure you have no ACTIVE widgets.
