I don't know much about this stuff at all but I'll see what I can do, Vista is VistaOS, I have administrator privileges, I don't think that I have changed any settings, there are no error messages, I have the white V in the red background icon on my taskbar but if I left click on it it goes black and vice-versa, no I haven't bought any cards yet as I just wanted to view the free version first, in the options I have unchecked the non nudity and checked all the others. I hope this helps:)
