All the programs in Office 2001 causes Mac to freeze on launch. Had 1500 email addresses in groups in address bk. Exported contacts & backed up but realised doesn't include groups. Where's groups info stored? Do I re-build database? Can't start Entourage in order to do this. What's causing whole Office suite to not work properly? Don't want to go ahead not knowing what I'm doing and make worse. Can anyone assist?
