Please save to a 2004 format

Greetings all,

I have a file that was generated in 2013 and I need it saved down to a 2004 format. 

My new office only runs ACAD2005 and I can't read the higher format.  I have tried to

run through true view to convert yet I still can't get it to change down.

Any help would be greatly appreciated.

Thanks

Rray
