I don't know when this happened. I had sent out proofs the previous night but when I opened the document, one of the spreads was blank. They copy looks like it is linking properly to the next spread but their isn't anything on the first spread. When I open time machine and try to copy the missing information and paste it into my document, it too disapears. What could make this happen. I use "copy as" when saving my file on a regular basis. I'm at a loss on what to do. Help!
