Game Fails to Launch - 1.7.2

[flarsh]

Hey guys! I think this mod is a fantastic idea, as I have had many builds on servers which I had no chance of retrieving. I've tried multiple times to get this mod to work, both with MagicLauncher and without, to no avail. I decided to try again, and post something asking for help.

Thanks a bunch!

(Running OSX 10.8.5)

Here's my crash report:

Doesn't look like a World Downloader bug. There is nothing WDL specific in this error message.
