This has happened twice to me. I renamed the theme in style.css and the entire theme reset itself and created an arbitrary theme style (green, really?). All the data in the theme was lost--ie, colors, customized functionality, etc.
I changed the name back to choices and everything was restored. Interesting. Maybe this will help someone in the future.
Create a new thread and tell me what problems you are encountering and what you want to know. 
There is no step 3 :)
