This file was a .stl file and I used an online converter to convert it to a .dxf. It seems to be all there but it is made up of a lot of little sections and I don’t seem able to join them at all. Check it out and see what you think. Thanks!

You posted the same unjoined file? Wondering why?
Increasing the DXF Auto-Close Tolerance may improve imported results:
Select all your shapes Done
Optimize selected shapes Done
Break Apart Unavailable greyed out
Auto-join selected shapes Unavailable greyed out
Do you have the shapes selected?
I do have them selected, yes
ver 2.0.05
Mine tells me no duplicates found
You have to Break Apart and Auto-join. Did it on 2.0.05 it´s the same.
Edit: I changed the order of my usual sequence 1.Break-Apart 2.Delete duplicates 3.Auto-Join. This is the correct order. You should get more duplicates.
Sorry about that.

I got it, not quite sure why it worked this time but it did. Maybe breaking for dinner was the key. 
Thanks for your input!
