just a FYI if any-one has this issue
when i downloaded the demo facial mocap for iclone it worked great except for no record button.
so i purchased it, then uninstalled from Iclone and the desktop, then a re-install after a restart the camera was blank or fuzzy and not connecting
I had to re-install the "realtek" driver for the camera, after uninstalling, reinstalling, restarting, adding the serial number too many times, and also sending the serial # to Faceware Realtime for Iclone
it works fine, I did get BSOD from checking all the drivers connected to the USB hub, but after a quick bios reset it is working fine
just too bad i do not see a toungue movement option for this
hope this helps any-one that the camera stops working after purchasing and re-installing
