mtXControl - a Rainbowduino Editor By Tobi

i have tried getting this to upload and work on my rainbowduino, and have been trying for months, and all it does is spew back at me Rainbowduino.cpp:0: error: expected constructor, destructor or type conversion before ‘/’ token

i am using a rainbowduino v2.0 and the latest version of Mtx control
