Okay, I built a ship after I unlocked all components in the game. That way I had everything to play with. When I saved it, the ship did not appear in my list, however, I know it saved as the ship file is saved on my computer with the name that I saved. I am able to send in the file if it would help to see why it won't show up.
I would post the picture of the ship unfortunately I can't locate it in game and the thumbnail file doesn't do it justice.
