It does seem that the option to save to an earleir version is not supported. A long shot might be to recover the BAK file (change ext to DWG) and see if that opens in MDT'04.

You have your file backed into a corner MDT is not bakwards compatable. I have seen people export a STEP file and bring it in to the previous version but you lose all of the structure.
