cannot upload to "me baseboard" (aka leonardo)

hi there,
i new arduino world , bought makeblock xy plotter. "me baseboard" apparently based on arduino leonardo.

i installed arduino 1.6.5 on windows machine running windows 7 , can find board on serial connection (com). when connect board attached stepper motors make short noise stops. 

however fail upload simplest piece of code board. when try upload kind of code error message:

code: [select]
