what it means to me is that what ever that update did was block my webcam from being usable it does not show up under devices and printers. it does show up in device manager and webcam applications but it gives the following error:

Can't connect to video source.
Please check another video capture device.

my current pc specs:
os: windows 7 64bit ultimate edition
ram: 4.00 gb
cpu: amd turion ii dual core mobile m520 2.30 ghz
hd: 320gb
connected devices: wd terabyte hard drive

please help me asap as i need this device for a video project
