OK so I have a board design (.brd) - specifically the Freeduino
http://www.freeduino.org/files/pre-freeduino_nkc_thru-hole.zip
How can I replace the 1 pin headers with 3 pin headers without having to add the part into schematic and then trace the board again from scratch.
I want to keep the board traces that were done already and just add in a part.
If I need to be more specific:
What I have : a schematic and board file ( that is traced already)
What I want to do : Add in a part into the schematic/board without having to generate a new board and trace that new board
Thanks

I think you have to go to shematic file, delete just the 1 pin header row, add 3 pin headers, reconnect the microcontroller to the new 3 pin headers and of course power and ground. Then you go to the board, you will have all the other pieces in place, just the new 3 pin headers will be to a side. You drag them to the place you want them to be and retrace from the microcontroller to the headers. Everything else will be in it's place untouched. If you still have remenance traces from the prevoius 1 pin headers, just rip up the old trace and retrace it manually.

Ok this is really wierd
I try to add a wire to the existing board in Schematic mode and it doesnt connect. I click the wire/pin I want my new wire to connect to and the wire is placed right next to it - not touching it.
Can someone try to download the files and add in a wire , they'll know what I'm talking about.
I'm on the same layer (91 Nets) as everything else , it just doesn't work.
What can I do so that I am able to edit the schematic?

The units are not set the same as the builder used when he designed that board. I had the same issues. You have to set the units and the grid to a very fine resolution, then move the part a little so the pins snap to the grid. Then the wire will connect.

how do I do that
EDIT:
You do View > Grid > then click Finest

I get an error when I try to modify the schematic :
Warning : Board and Schematic Not Consistent ! No Forward / backannotation will be performed .
How can I get around it.
-
Modify the schematic or modify the board? I only see that error when trying to modify the board (not allowed).

I ALWAYS get that error, it's so annoying.

when I try to edit the schematic and switch to board so that the board updates with the new components.
@Trumpkin - I feel your pain
