IDE 1.5.2 Crashes on Startup

I am not sure if this helps. But have had same problems with hardware folder with the Arbotix hardware which is used a lot on http://www.trossenrobotics.com/ robots using Robotis servos and the like. When I use their released version of the libraries/hardware it will crash the IDE. Over the last few days they have created a new fork of their stuff on Github that is supposed to address this. So you could always download both versions of their hardware folder from github.
