I bought the VX-3000 yesterday for my Vista Ultimate 64bit Edition.
Basically i installed it, Messenger crashes/black screen etc whenever i
tried to use it.
the software that cam with the camera gave me white screen followed by black
screen, 9 times outta 10 it would crash the application too.
i downloaded hotfixes from microsoft, no effect.. checked my drivers were
1.4, they were.
formatted my PC, still same problem.
I remember reading (i think it was on MS website) there was issues with
Nvidia USB ports etc, so i updated my motherboard drivers.
(directly from nvidia for the chipset, not my motherboard manufacturer)
Seems to be working perfectly fine now.
So if you've got Nvidia chipsets (nForce / 680i etc) and ur having the
problems i discribed above then download the latest chipset drivers from
it worked for me.
If u dont have a nvidia chipset, then sorry im still clueless
