Task Scheduler Error message/cannot run

For some reason I cannot open Task Scheduler. When I try to open it says
"Task Scheduler service not running. Verify that the service is running."
In services.msc it says that it is "started". I would stop and restart it
but the options are greyed out. Get an error messenge where I try to stop
it via Task Manager services tab.

I have tried net start "task scheduler" in cmd.exe but everytime i try to
start task scheduler it says its already running (when there is oviously a
problem with it) and when i try to stop it i get an error message, access
denied. I have UAC turned off and did "run as administrator".

Also i try to add the snap-in within the MMC.exe but once i add the task
scheduler snap in it says service not available, verify it is running.


Any ideas?
