help noob with arduino and flash please

hi there,

i just got my arduino uno starter kit and am a little confused. i got glue2 and serproxy already. i did install the standard firmata firmware on the arduino, edited the config file of servproxy to my port. when i start servproxy and then start the blink example of glue2, servproxy tells me "server thread launched" and "server6 thread started". so i guess i did the setup right. problem is, the led connected to 13 and gnd does not blink. it does blink during the reset function (when i press the reset button) but then its dark again.

would anyone help me please? thank you so much!
