If you have/use any MS DAO 3.5 references or less than 3.5 in your VB program, you'll need to update these to 3.6 minimum for the VB program to access the database. At least, I think 3.6 - I'm not at my work PC at the mo so can't double check. Use the highest version you can....

It might not be an issue for you, but it came up with me a few months back when a customer needed to upgrade from access 97 to access 2000 and our VB app disagreed.
