First, please download the 1.6.6 beta. There have been a lot of changes to the DDT and the import process between versions. You can get it here: http://forum.strataframe.net/FindPost16061.aspx.We will be posting another beta later this week with even more changes to the DDT. The DDT has been getting a lot of attention lately and will have many new features and enhancements through the next several releases. So try the same process on the 1.6.6 beta and then we can work from there. Thanks.
