Problems with Access db files after migrating to a new version.

[Elyfete]

A week ago we have migrated to a new Access from old 2003. But after this event we experienced the problem with any .mdb files. No one opens. Instead we are getting the next error: “An error occurred while loading Form_FormName. Do you want to continue?” I click ‘yes’ button and then get another one error: “Invalid procedure call or argument”. The reason might be migrating on the other version, I thought. Can it be? If yes, then we can approximately imagine what we should do. If not, we have no suggestions…Anyone experienced such problems?
