SOLVED - I just wanted to write a final note to wrap this up. Since a 23rd Century character can only move in one "instance," there is no way to free a ship (or character) who is trapped by changing instances. The good news is the Arc Games support was able to extract the ship, and get me back in the game. Use the ARC…
I am glad to hear that someone else has at least had this problem. I will try one (or both) of those ideas. They sound like a great place to start. I think the only problem with the transwarp was that I didn't have enough money (being a new character). But I can probably transfer money from one of my other characters.
