Right-click on the device tree on the left side of MXEditor and a selection window will appear. Select "Import Device" and find your .mxd file. In the next window, highlight it and select where you want it to appear on MAIN page 1 or 2, then click the "RIGHT" arrow. The next box that pops up is "Device Assign". You must highlight each device that appears under "Used External Devices" and assign it in the pulldown box below. After you've assigned each device, the "OK" button will no longer be greyed out and you can click it to complete the import.
