Now I've done it. I was goofing around changing the theme color for both md and txt formats, and somehow I blew it up. I click to open the app now, and it doesn't open. The last error I saw was something to the effect that there was no data in plain text.sublime-settings:1:1. I opened that file in Notepad, copied in setting from another theme, but no dice.
Any clues as to how to proceed?
