Lifechat LX 3000 and Windows Vista Home Premium

I just purchased the Lifechat LX 3000 and the ZX 6000 and neither will work
with my 32 bit Windows Vista Home Premium system. I installed the Lifechat
1.0 software and followed all instructions. As far as I can tell the
software loaded fine. The system recognizes the LX 3000 but tells me it can
not find the driver to make the headset work. As for the ZX 6000 it
recognizes the receiver but not the headset and again tells me there is no
driver loaded. What am I missing here? I've checked under Device Manager
and I am not given the option to choose my headset etc... I've gone to
Microsoft's hardware page, uninstalled the software and re-installed using
the downloaded version. I've always used Windows Live messenger so what's
left? Any help would be appreciated. Oh and yes all sound card drivers have
been updated as well.

Thanks for any help you can give.
