Boot into Safe Mode by booting with the Shift key held down and try NeoOffice from there. Reboot normally and test again.
NOTE: Safe Mode boot can take up to 10 minutes as it's doing the following;
Verifies your startup disk and attempts to repair directory issues, if needed
Loads only required kernel extensions (prevents 3rd party kernel/extensions from loading)
Prevents Startup Items and Login Items from opening automatically
Disables user-installed fonts
Deletes font caches, kernel cache, and other system cache files
