Hi All,
I bought 2 x VX-3000 webcams. the first one installed fine on an XP machine.
So now I've started installing the second one on my Dell laptop (600M w/ WINXP).
Software installed OK.
Then the lifecam software ran for an update...that was OK.
But when I run the software the preview screen is Black!
In short...I start up the lifecam software, it says "Connecting....", and then words dissappear, and I get a black BOX 
I chose the "Audio & video Settings" under the Lifecam Menu.
I can hear the audio test, the microphone works and I can see myself during the video setup.
Then it finishes....and the lifecam software says "Connecting.....". But the screen stays Black.
Here is the wierd part. If I press the video button(on the lifecam software) it starts recording, but the lifecam screen stays black.
But! If I go to the video I just recorded and play it...its fine!/ Color is there and video looks great.
(When I take pictures, they stay Black)
I've tried changing the resolution values in the lifecam software. No good. I've tried going into the DEVICE manager and deleting all USB peripherals and then reboot. It's all the same. Black screen!
Also note. If I go into Windows Explorer//My Computer//VX-3000. I can see myself! My webcam works there.
I tried installing the Logitech software from the link,listed in a previous post by Clueso (Microsoft-suggestion) but that didn't do anything for me!
This is driving me nuts!!!
I want this fixed.
I also noticed that in my Device Manager, under "Imaging Devices", I only have one item which is the lifecam.
But it says "Microsoft Lifecam VX-3000 #3"
What does the #3 mean
Hopefully someone will figure this out!!
