The first thing I would try is to open the database with the data sheet only. You can do that with the Find & Open dialog. Open this dialog (from the File menu), locate the database in question, then right click on it and choose Open Data Sheet Only from the pop-up menu. If this works, the problem is either in the .Initialize procedure (if the database has one) or in one of the forms. I just checked your crash logs from this morning and it appears that the crash is occurring as a form is being displayed, specifically as a Text Display object is being displayed.
If it possible for you to send me a copy of this database, I would be interested in attempting a more detailed investigation.
