SilentHunts,
Thanks for your reply.

I installed TheDarkWraith's new UI mod, but the forward tubes where not repaired. I then went to port for a refit. The tubes where still not repaired.

So I had to end the patrol, and start again with the loss of the two ships that I sank previously.

Now when i start the game, by clicking on the saved game, it closes to uplay.
