This may, or may not be related but ....
A few days ago I let the 'Windows update
service' install a new driver for the 'Intel
PC Camera Pro'. That blew away my VA11A
driver and made the video quit working.
After getting the VA11A working again, my
one camera was changed to an 'appliance
module' or some such thing so I just changed
the module type back to 'camera'. After that
every time I hit 'On Air' AHP would crash.
I finally cleared the problem by deleting
the camera and associated macros (saving and
downloading) and then adding the camera
module back.
I did not spend a lot of time investigating
this but it would appear that AHP will
change the camera module into something else
if the video interface is not working.
Changing it back to 'camera' after that
makes AHP crash when you try to see live
video.
Good luck with your problem.
