CTD On startup 0.9-814-gde9bdf9

When I start Cataclysm, I get this error:
data/json/colors.json: line 2:5: unrecognized JSON object, type: "colordef"
I have windows 7. What do?
EDIT: Deleted the CataDDA folder, re-downloaded it and it worked. Weird. Maybe it has something to do with the fact that I updated from a previous experimental?

Yes, we’ve been shuffling around files a bit, and it was trying to load an old file.
