[Solved] Can't get started with USB example

Board: Arduino UNO
Browser: Chrome 50.0
OS: Windows 10
IDE: codebender
Blynk: v0.3.7 (I use the scripts only, for uploading the sketch I use codebender)

when I run the following command as Administrator
blynk-ser.bat -c COM4

I got the following:

On the phone it keeps telling me that:

Your Arduino UNO is not in network

Update 1
I’m trying to switch pin 13 to control the attached led at UNO

Update 2
Installing the library and uploading the sketch via Arduino IDE 1.6.3 works.
Seems that codebender causes the issue
