2.0 keeps crashing

Note:

2.0 client itself shouldn't be bugged, because I see others play it.
The .jar and .json file I downloaded shouldn't be bugged, because I used the link in the wiki page for 2.0 (http://www.mediafire.com/file/f526l5zp09k3k86/2.0.zip).

So it should be with the launcher. Or if the link in the wiki page has not been updated? Because the link is for "Download for the Current Launcher", and the launcher was updated just recently.

Anyway, this is the crash report:
