dumb question but is there literally a theme called "new theme" or are you just talking about the new default sublimetext theme?

There is a brand new theme, called simply Default, that ships with Sublime Text 2. See:

http://www.sublimetext.com/blog/articles/sublime-text-2-buil...

If you've customised your theme already, you'll need to go into Global Settings > User and either remove the theme line or change it to:

  "theme": "Default.sublime-theme",
