Hello - I need help! I was working on a rather long file (30 + pages) when I accidentally hit the "Insert catalog pages" button. It took me somewhere I didn't want to be and did something to my file. I am unfamiliar with catalogs and didn't know how to get out of it so I just closed the file without saving, thinking I could reopen it as normal from my last save. but now I can't open it! It says "Publisher cannot open the file". I have days of work in this - can someone help?
