The first step is to figure out if it is the app or the data file.

Does it launch under another user account on your computer? If so, then the problem is more likely the data file or preferences. If not, then the problem is more likely the application or its global preferences file.

To find out:
1. Go to Apple Menu -> System Preferences -> Accounts
2. Create a new account
3. Log into that account
4. Launch Now Up-to-Date & Contact
5. Report back what you find.
