Outlook crashes when opening/accessing address book

Hey guyz, everytime i try access address book, my outlook crashes, same thing if i type in an email address and it searches to address book for a match, so pretty much i cant send emails because of this..

Any ideas?

one possible cause of this could be enlargement of your .pst file. to check if this is the problem, try creating a new profile then observe if the problem still occur.
