I've made a fully-functional database on Windows XP (Office XP). One of the computers it needs to run on operates Windows 7 (also Office XP). When I open the document on its own, no problem. When I open it from the database (using a button with a hyperlink), it says that Access has encountered a problem and must cancel or some bull like that.
I haven't a clue where to start with this and urgently request any help you can give. (Deadline coming up! Must get paid)
