Task Scheduler error and language bar

[Yuxi]

Hi,

I noticed sometime after installing SP1 that my language bar no longer appears. After some research I think the problem has something to do with the Task Scheduler, so I open TS and get an error saying:

"Catastrophic failure (Exception from HRESULT: 0x8000FFFF (E_UNEXPECTED))"

If I run the "MsCtfMonitor" task, the language bar comes back until I log off.

Also, I checked the event log and noticed that every time I log on, the Task Scheduler generates an error:

"Task Scheduler service failed to launch tasks triggered by computer startup. Additional Data: Error Value: 2147549183. User Action: restart task scheduler service."

Any ideas? I'm using Vista Home Premium 64-bit.

Thanks.
