Yikes! First go out and buy a cattle prod so as to ensure this does not continue to happen.
In the future have a process mapped out were the sales person starts the project file in TEXT.
The engineer can then open that same file in Visio later.
But for now...hmmm...lets try this.
First! Copy both files to a USB stick or burn to a disc, remove from the computer and place in a safe spot across the room.
next: Pick one file to be the new master. Save the Xtra file to the local drive of your machine. Open the new Master file and then do an insert system and insert the Xtra file into the master file.
Then clean up the redundant stuff.
Then archive the Xtra file if using the business manager or delete if not using the business manager.
Kind of ugly but this should do the trick.

If not, you have copies of the original files and you may then need to a "do over file".
Shoot me an email if you want me to have a look online.
