lifecam vx3000 stops windows from starting

I installed Lifecam XV300 on my windows vista laptop last night and
everything worked fine. I turned the comp off overnight and when I started
it up again this morning, Vista could not start. I got a message saying that
Windows would search for a solution to the restart problem. After ten
minutes, it came back and said it could not fix the problem. It said the
problem was caused by a device driver. Well, since the cam is the only thing
I've installed on this comp lately, I know that's the problem. It took me
forever to figure out how to get Windows to start and one random time it
finally did, but now I'm afraid to turn my comp off without figuring out how
to fix the driver issue first. Has anyone had this happen to them or know
what I should do? Thanks.
