Hey, I recently bought an Adafruit Motor Shield 1.1, but i'm having problems programming it. Everytime I try to upload a program, it tells me it cant find the COM4 port, only the COM3, which doesnt finish uploading. Also, COM4 works fine when I detach the motor shield and play with LED's. I'm only a beginner, so I have no idea what to do.

Some shields interfere with the upload 
detach it when programming
I don't know if this is cross-posting, but it seems that you have a single problem. So it would be better if you started a single topic, instead of four.

vek11,
Which Arduino board are you connecting to?
I have used the Adafruit Motor Shield with an UNO without any problems uploading. The Adafruit Motor Shield does not use pins 0 and 1 specifically so that it will not conflict with TX/RX.
Eried, I detached it and uploaded the program to the Arduino, then attached the motor shield, but nothing happened.
Louis David, i'm using the shield with an UNO.
