Dear Mr Cruz,I followed your explanation as you will see in the attached video and no issue resulted on my end. I am sorry to hear that the issue still persists for you. When you installed AS 2017 did you follow the procedures below:To convert the databases from the previous version, proceed as follows:Start Management Tools: Start > All Programs >Autodesk > Advance Steel 2017 > Management Tools 2017In the Management Tools application window, select Convert Databases.Next, click the Open Database icon, in the top left corner of the Management Tools window.From the Open dialog box, select the old versions of the databases (*.mdb files) and click Open.The conversion tool will automatically recognize the equivalent Advance Steel 2016 database to which the merge is done.The database is loaded. Only the tables that can be converted are displayed.Select the tables to convert and click Convert.Perhaps you could try a repair or uninstalling ACAD 2017 then reinstalling it.Best regards,Janet
