Have you tried the "Detect and Repair" option from the Help menu in Office 2000, stourry? You could also try turning off the Error Reporting function in XP:
Right-click My Computer and choose Properties.
Click the Advanced tab on your System Properties dialog box.
Click the Error Reporting button on the Advanced tab.
Place a checkmark next to "Disable error reporting."
Leave the other radio button unchecked next to the text labeled, "But notify me when critical errors occur."
