Hi,
Looks like you are trying to open a higher version file. Can you attach the file here? I will try to save the file in lower version that is compatible with MDT 5.
Note: If the file is created in AutoCAD, then I have an option to save it in lower version. If the file is saved in MDT 6 or above, then downward save is not possible.
Thanks,
