Hi
I have a word file contains more than 100 pages.It will open normally a few times after saving it. but after 4-5 times opening the file it gives error….The file cannot be opened because there are problem with the contents  Details:"The name in the end tag of the element must match the element type in the start tag.Location: Part: /word/document.xml, Line: 2, Column:809459".

The issue of not being able to open a file in MS Word, and getting the end tag error message can be related to the oMath tags. This occurs when a graphical object or text box is positioned in the same area where the paragraph contains the equation causing it to have a conflict with the format. There are many ways to have this issue resolve. If you are using the Microsoft Office 2010 with Service Pack 1 it actually can solve this issue for new files. Plus, it will also help you prevent this kind of problem from recurring in the future.
