We have a System file that closes WQS [crashes] with the following error - "The Microsoft Jet database engine could not find the object 'Databases'. Make sure the object exists and that you spell its name and path name correctly." Recovery was to revert to an earlier backup, but lost a lot of edit time and user is not concerned the problem could repeat. At the time they were adding reference designator information - which would be mostly text field updates. Has anyone experienced this issue and determined a cause or fix?
