HELP....Where can i find backup software for webcams?

From you comments

I purchased a Logitech quickcam Messenger 2 years. Then, last month Crashed my computer, and I had to reinstall Windows.

I lost the CD for my webcam software, Is there any way I can be downloaded from the Internet, without paying anything or something?

Do you need to work hard for the cam?

I do not know what to do.
