Commonly a divide by zero error. Is this the first number? This is usually preceded by something like
STOP: c000021a (Fatal System Error) (or even a different "STOP" message).
Have you processed all of your updates for adobe after install? Tools-Check for updates. Then try combining.
Yes, I have done all of the updates. I have found that if I make any changes to the photos and then try to combine them that is when the error occurs. (If the pic is dark and I lighten it up)
