Serial USB connection problem

After I upload the sample sketch, the serial port only shows my Token over and over again and my brower is constantly wating for connection! I am using Windows8, so i did these steps as instructed:

1. Open the Windows command line (cmd.exe)
2. Navigate to the scripts folder by typing "cd [path]", e.g.  "cd C:\Users\pc\Documents\Arduino\libraries\Cayenne\extras\scripts"
3. Run the script by typing "cayenne-ser.bat -c COM4" (where COM4 is myport with your Arduino) and hitting Enter

Is there anything else i should do to set up the serial USB connection?

After i hit the enter in command window when i was trying to run the script cayeen-ser.bat by using the same coding “cayenne-ser.bat -c COM4” . However. the command window just seemed to crash. COM4 is just the right port for my Arduino Mega! This pic below shows what happened:

Please Help!

Welcome to Cayenne!

Can you give the full error message? Looks like that may have gotten cut off.

Note for serial usb to work you cannot have Cayenne debug running. There should be a note in the sketch header.

Can you confirm?
