Pages are transposed in document.

I have been using CorelDraw X5 for three years to lay out a magazine. It worked fine under Windows 7, but I was forced to get a new computer with Windows 8. When I loaded CorelDraw, I got a message saying that it would work, but there were "issues".

Now one of those "issues" has apparently cropped up. CorelDraw is transposing some of my pages. The last two pages of one article are moved into the following article, and the first page of the following article is moved into the preceding article. If I move them back where they belong, Corel just moves them again. This is not only frustrating and annoying, it's eating up my time, and I'm on a deadline. Any suggestions?
