"The first step whenever Word crashes.

Close Outlook and press CTRL+ALT+DEL to open the Windows Task Manager. Check the running processes to ensure that there are no stalled instances of Word still running, and if there are, end those processes.

The crash will have left a selection of temporary files in the current Document folder for any document that was open at the time, in the Word Startup Folder, in the Office Startup folder, and at other locations depending which global template add-ins you have installed. These temporary files can impair the future smooth running of the application and should be deleted. See http://www.gmayor.com/what_to_do_when_word_crashes.htm
