I created an Access DB using Office2K Professional and I am using the Startup option to load a form when the program opens up. The database was working fine. Recently at work I got a new computer which had Office 2003 Professional installed on it. I need to make a few changes in the Access DB using Office 2003. I made the changes and saved. Now when other users who have Office 2K on the computer can't run the program. I checked under Tools --> Options --> Advanced Tab --> Default File Format = Access 2000. The file work fine with Access 2003. Any ideas?
