[AC-1133] [Error] : Failed to encrypt JavaScript files (Windows, upon connecting an android device)

As soon as I connect my Cubot GT99 phone (running rooted Android 4.2.1), Titanium studio refuses to complete builds on the step 'Encrypting Javascript Files' As soon as I connect another device (An oldie, running android 2.3.7) the same thing happens. As soon as I connect a Samsung Galaxy Camera, the same thing happens. As soon as I remove the connected device, I can once again run the build process and deploy it to the emulator.
