Hi.
For all those who are having problems with Youcam 5 Delux and asks me why don't I have them, and what are my configurations etc..
I don't know why is this happening to You, I don't know the issue and how to solve it, it just works for me.
Using PC Windows 7 Ultimate, core i3, 255 hdd, ati amd radeon hd 5670, Norton Internet Security, UAC settings are disabled, DirectX 11 also installed DX 9C, USB 2.
That's all I know, hope this helps.
