I've been creating a photography book for about three weeks. The document elements are basic: text and imported/linked JPEGs. I started with 1.7.3 and continued with 1.8 as of the day it was released. No problems until yesterday morning. The project consists of two Publisher documents: 1) Cover (500K) and 2) Pages (700MB). The book has gone through a number of revisions and I've kept earlier versions of both documents. The issue I'm reporting began occurring yesterday morning as I was doing final edits: Publisher began crashing (I see the UI for a split second before Publisher closes) on the 'Pages' documents (current and previous versions) only. All of the 'Cover' documents (current and previous versions) open. I had been fine tuning the most recent 'Pages' document, updating a few photographs, saving, exporting a PDF to verify, with no issues. The 'Pages' documents crash began occurring when I went back to do some final edits on the latest 'Pages' version which I had been working on and had closed subsequent to exporting a PDF.
To reiterate: Publisher crashes when I try to open any of the 'Pages' documents, so the issue is not related to the most recent 'Pages' document I was working on, but loads and opens all of the 'Cover documents'. Also, If I load Publisher, open a 'Cover' document, then try to open any of the 'Pages' documents, Publisher crashes. I re-booted twice with no effect. I'm using a Windows 10 PC laptop on which Publisher has been running smoothly and without issue beyond an occasional 'not responding' which clears after a few seconds. I submitted a crash report the first time the crash occurred but did not include my email address as I did not know I could do so at the time. I tried re-installing 1.8 over the existing installation with no effect.
UPDATE:
24 hours later I just tried uninstalling 1.8, rebooting, then installing 1.7.3. 1.7.3 would not open any of my documents since they 'use features from 1.8' or words to that effect. I then uninstalled 1.7.3, rebooted, then installed 1.8 again and am back to where I was yesterday as per above. Is there anything else I can do to move ahead with the book project which I need to send out to get printed.
Thank you in advance.
