Hi Sonia...
No Apologies are needed. And I doubt you have the wrong information.
I believe these links I found for you should provide drivers that work.
As for helping you further...
LookinAround is actually better at this than I am,
and he was the one who wrote this tutorial.
Maybe he will jump in with some guidance.
From your note, I am assuming that you were able to use the downloaded drivers to try to get your camera to work.
Could you describe, step by step, what you did?
And ... meanwhile, to try to help you get there...
1. Do you have a brand on the webcam? (This might provide another angle from which to search.)
(Though often the same drivers will be used by hardware sold under multiple brand names).
2. What operating system are you running? (XP, Win7, other?)
(The exact steps will vary a little, though if you are computer savvy, you can usually make the translation)
IF Windows reports that your driver is up to date, and the device is working properly,
your issue may not be a driver issue, but rather a utility with which to use the Camera.
This is one possibility for you, available here on Techspot.
Alternatively,
There are a number of free utilities on CNET.
PLEASE BE AWARE...
CNET downloads include use of a system that tries to get you to add unneeded and unwanted software.
If I were you I would uncheck any software they want to load on your system
besides the particular software you wanted.
Watch the installation process carefully.
Assuming that you really do need to update the driver,
Either LookinAround, or I, (or another) will step through a process for you.
