Arduoblock with new Arduino software update

Hi! I'm getting this error code when I use Ardublock with the newly installed Arduino software. Please advise. I'm trying to work on a project to use with my sixth grade students. Thanks!

Exception in thread "AWT-EventQueue-0" java.lang.NoSuchMethodError:;)V at com.ardublock.ArduBlockTool.didGenerate( at com.ardublock.core.Context.didGenerate( at com.ardublock.ui.listener.GenerateCodeButtonListener.actionPerformed( at javax.swing.AbstractButton.fireActionPerformed( at javax.swing.AbstractButton$Handler.actionPerformed(

Are you using Arduino IDE 1.6.12? If so I'm guessing you're encountering this issue: You should be able to solve it by using a previous version of the Arduino IDE, 1.6.9 was a pretty good one.

The Arduino developers have notified the ArduBlock developers so I'm guessing the problem will be solved by the next ArduBlock release.
