I have uninstalled the program and reinstalled it three times using the following instructions from this link as well as read threads with others having the same issue but I can't seem to fix it. Now all of a sudden, for no apparent reason, it crashes when I start, Excel, Word, or PowerPoint. I have been running MS Office 2011 for Home and Student on my MacBookPro (OS 10.6.8 ) without any problems.
