Hi Ldufresne19,
What is the version of the ms access in this pc? it should be ms access 2003 or greater. I have experience same problem using msaccess 2000 to run the application made from ms access 2003 (although the format version of the mdb is 2000), for some reason my ms access database does not work. switching to ms access 2003 solve the problem.
good luck.
