Shran,
A couple of questions for you regarding the Universe.
How about the ship, was she destroyed or did she manage to make orbit, before she was abandoned? Was any of her equipment and technology was salavagble?
How Many Crew aboard her? How many survived? Where there any other ships dragged along with her? e.g. Klingons;
There is a couple of suggestions for you:
Option 1: The ship was crippled, but most of crew survived and were able to colonise the planet using the every surviving scrap of technology and equipment available to them, even so they have regressed to mid-21st Century Technolgical Levels;
Option 2: The ship was destroyed in the accident, the surviving crew was able to get to the escape pods, but where scattered over the planet, they set up several small colonies, but their technology regressed to mid 17th Century Technolgical level.
Does this help?
