Problem With Open SmartWatch IDE

Hello everyone, I'm trying to create a program for the sony smartwatch.
I have found this guide
http://developer.sonymobile.com/2013/06/19/open-smartwatch-project-arduino-publishes-tool-chain-alpha/
with the GitHub Project

I'm using Ubuntu and I downloaded the IDE for linux but it doesn't work, it does not open.
The normal IDE works perfectly with the arduino board.
Can someone help me?

Thanks in advance for any response.
