Windows Desktop Gadgets has stopped working

Windows 7 and Windows Desktop Gadgets have always been working fine lately until I installed my new Logitech E 2500 webcam. Every time when i start my computer an error will appear saying that Windows Desktop Gadgets have stopped working. I read the solutions in
Gadgets Stopped Working
and
Windows Gadget has stopped working error!!

but none of them fixed my problem. What else can I do to fix this?

Thanks.

I also tried restoring to default windows 7 gadgets, but when i press "Restore desktop gadgets installed with Windows" the error just pops up again.

@Orbital Shark
I downloaded and installed the latest driver. The driver the company provided from the CD made my Windows 7 unable to load at all so I had to format Windows 7 again.

@Tews
There was a warning prior to the error but I don't think it has any relation with the error.

Thats interesting exousia7 - the same thing happened to me. The last thing I installed before the gadgets stopped working was my Logitech Orbit AF webcam. The drivers I got from Logitech's website, and they were Vista 64-bit drivers. The exact same thing is happening to me, I can't even restore the gadgets.
How do I check the event log?

So I uninstalled the Logitech Webcam application but kept the drivers - surprise surprise, the gadgets work again! Interesting though eh?

oh nice.. thx andd64. i'm going to try this out...hope this works.

Same. I installed the software for my Logitech Quickcam Pro 9000 and the gadgets died. I uninstalled the Logitech software (not the drivers) and they came back immediately.
