Error message (case 416)

When I moved an IAT task to a laptop computer I started getting this error message:

I was wondering if you might be able to help with addressing this problem?

Check to see if the bit depth of your image files is 8 bit. Simply right-click the image file, select Properties, and then the Details tab.
