I found that while I had updated my Java SDK and JRE my actual version of Java wasn't updated and my system was cluttered with 3 different versions. After taking off the old versions of Java and loading the newest one Brainflex.jar now functions perfectly.

Now I just need to dig into the source code so that I see how to capture the data and perform a bit of math on it.

I'm still trying to get VLCJ Player to function - will try rebuilding the .jar file.
