I was attempting to back up a large database file (35,000 records) from my laptop to another computer over a network. I copied the file from one computer and pasted into the other. Played with it to be sure that it was ok, and everything was fine. Then the next day I went to open the database from my laptop and got the error message: "The Microsoft Jet database engine could not find the object 'MSysDb'. Make sure the object exists and that you spell its name and the path name correctly." I got this on the laptop and other computer. I cannot open the database, import information from it, or anything else. Basically 139MB of wasted space. I'm DESPERATE!!! I didn't have any "objects" that I know of (forms, reports, queries, etc.) named "MSysDb". I can't understand why I get this message or how to get into my database.
