I am having a lot of trouble getting maxuino to work on my arduino uno rev3 (windows). I am using the arduino-023 build and uploaded StandardFirmata on my Arduino, This is going great. Now the real problem.

When i open de Maxuino_014 Max Patch, i get the error: specified port not available, witch its strange, because it is saying Com4, and that is the right port, the arduino program uploaded firmata trough Com4 and i have not changed the usb connection (also tried that, did not work).

Can any one help me with this? It is for a school project and i really want to make something cool!
