I have been working on this project since September and I have a presentation next week! Everything was working fine until today!

No matter what I try to run on the EV3 it just beeps and gives an error:

Uncaught exception:

java.lang.UnsupportedClassVersionError
move : Unsupported MajorMinor

I have tried re installing the plug in and I have tried using an older JRE so im really stuck and in a panic.

The program I am trying to run at the moment is simply moving the two motors, I have even tried a simple 'hello world' program but nothing runs.

There was another version of OpenCV in the library. If any one else gets this error it may be worth checking all the installs and libraries
