How do I get the new driver for my Insignia camera?

-When I bought my camera I installed the driver that came on the CD. But that was months ago. Now when I plug it into my computer it says it can't recognize the camera because there's a driver that needs to be installed. It still says the old one is installed though. I checked the computer files to see if there was something in there that could help the problem but it came up empty. Where or how would I find/install the new driver so I can get back to uploading videos.

Thank You.
