Skype video Upside-down with LifeCam VX-6000

[refresh7]

My grandfather has a MS LifeCam VX-6000 and uses Skype to chat with
me. Since last week, his picture is upside down in Skype. He said he
didn't do anything and the camera is not physically upside down. What
could be the problem?

At the bottom of the picture do you have a bar with rolling arrows?
If so, click one of them.
If not, try clicking Ctrl+Alt+the up arrow.

Sorry, that's all I have for now,
The only other thing I can think of is for ViewSonic software,
Control+Shift +R
