I attempted to install my StampManage Deluxe 2015 update today. When I booted the program I received this message: The changes you requested to the table were not successful because they would create duplicate values in the index, primary key, or relationship. Change the data in the field or fields that contain duplicate data, remove the index, or redefine the index to permit duplicate entries and try again. I have no idea what this means or how to proceed. I guess I do have duplicate entries as I collect both single and coil pairs. But also missing were stamps 1,9,24,63,65,68,69,and 70 which had my photos attached I have no idea what else is missing. Dave Theobald It seems that all my stamps are present but the program is identifying stamps by the ID number rather than the Scott # any way to change this? Thanks
